Website almost ready for launch!

Dear readers,

I would like to introduce myself as the new voice of the HMS Challenger blog.  Heather’s last day at RAMM was on Friday and I will keep you up to date from now on.  I am Holly, RAMM’s Collections Officer.

This will be a very short post just to say that the Challenger website is VERY close to being launched. Here’s a sneak peak of the home page … still needs a bit of work but they do say a picture paints a thousand words.

Challenger Website

Data will be added gradually over the next month or so and I’ll let you know when it goes live! Exciting!

Quick update on the HMS Challenger Project and useful resources

Hello all!

Firstly – sorry it has been so long since I have written a post. It has been manic here! Whilst I am trying to get through a lot of data work and disappearing off to Ireland and Cardiff (for the second time), Holly has been starting to write some website content and disappearing to Manchester (also for the second time) to take some more images of their Challenger material. The website is nearly here! Fingers crossed it should go live by the end of the month (but don’t take my word for it!).

For those interested in reading more about the Challenger expedition here are some resources you could use to help you:

The Challenger reports online

This website has been tremendously useful. It contains pretty much all of the Challenger reports, including the narratives. Brilliant for double checking specimen labels.

Informative books

    • The Silent Landscape: In the Wake of HMS Challenger 1872-1876 by Richard Corfield.
The Silent Landscape In the Wake of HMS Challenger 1872-1876 by Richard Corfield

The Silent Landscape In the Wake of HMS Challenger 1872-1876 by Richard Corfield

This book has been great to read up on the voyage – easy, informative read that takes you right the way through the voyage.

    • At Sea With the Scientifics, The Challenger Letters of Joseph Matkin by Philip Rehbock.
At Sea with the Scientifics by Philip Rehbock

At Sea with the Scientifics by Philip Rehbock

This book gives you the voyage from a different perspective. This book is full of letters written by Joseph Matkin, the ship’s steward assistant. He takes us on his own Challenger journey.

    • Notes by a Naturalist on HMS Challenger by H N Moseley.
Notes by a naturalist on HMS Challenger by HN Moseley

Notes by a naturalist on HMS Challenger by HN Moseley

This book is different yet again. Moseley was one of the scientists on board. Rather than concentrating on what was dredged and trawled at sea, Moseley concentrates on the actual land areas the ship anchored at. He talks about subjects such as the landscape, botany, the people they meet and the culture.

These are definitely some of the best resources on a variety of subjects to do with the HMS Challenger voyage.

Going back to talking about the project, I  (Heather) will spend my last day at RAMM next Friday so it is time to say goodbye. It’s been an amazing year and I don’t want to leave! I will be staying in Exeter though – going to study an MSc in Zooarchaeology. So you never know, I could be back to write again! (Don’t worry though, a post will go out when the Challenger site goes live!)

Bye everyone!

BBC’s The Long View Compares HMS Challenger to the Space Shuttle Programme

Three of NASA’s five space shuttles were named after British exploration ships – the Discovery and the Endeavour after Captain Cook’s ships; while the ill-fated Challenger, which exploded on launch in 1986, was named after our very own HMS Challenger.

HMS Challenger and NASA space shuttle Challenger

The connections are very appropriate, in fact. Not only were the Challenger expedition and the space shuttle flights both landmarks in their respective worlds of science, they also have similar undercurrents of political and military involvement. Both programs were born of world powers wishing to show their technological and financial prowess, and what better way to do so than to fund scientific expeditions to gather new knowledge about little known environments? Also, while HMS Challenger had most of her guns removed, she and all her officers still belonged to the Royal Navy. Just as the Royal Navy stood to benefit from new knowledge about the ocean in the 1870s, so the US military benefited from NASA’s ballistics and physics research.

Finally, the space shuttle programme was cancelled by budget cuts in the US government. When HMS Challenger returned home in 1876, the expedition also faced funding problems. The government grew disappointed with how long it took to produce the reports and one of the Challenger’s scientists had to put a lot of his private money into the project.

This BBC Radio 4 programme from 2011 (when the space shuttles were decommissioned) explores these similarities and more. It’s only half an hour long, and well worth a listen!

Scientific Equipment on HMS Challenger

Hello! This is Peter (the Challenger Project’s volunteer) writing. I’m a history student at the University of Exeter, and I’ll be working here until the end of June.

This map was made using data from the Challenger expedition

This map was made using data from the Challenger expedition

As you probably know, the Challenger project is bringing together data from museums all over the country. It’s great that there’s so much information, but it can be pretty overwhelming! HMS Challenger stopped at over 400 locations (at 354 unique stations) during its trip around the world. At each of these stations, the crew and scientists took detailed scientific readings about the sea and the weather with barometers, hydrometers, thermometers and other instruments, as well as dredging or trawling the seabed for specimens. Just the data we have amounts to well over 15,000 specimens! So far, most of what I’ve been doing is going through spreadsheets of information, matching up station numbers with data like ocean depth and temperature, or filling out taxonomic data for several hundred specimens (so far!).

This temperature data was collected by the scientists on board the Challenger.

This temperature data was collected by the scientists on board the Challenger.

Something more interesting I’ve been looking at recently, though, is the equipment used on board HMS Challenger. Though the Challenger was a corvette, a small war ship, most of her guns were removed to make way for all the scientists, their equipment, and a pair of laboratories. A small steam engine was also fitted to the upper deck, to be used as a sort of winch for towing, raising and lowering the dredge and trawl. The dredge was a net fitted to an iron frame which would be dragged along the seabed on a long rope, stirring up the bottom and scooping up samples. The trawl was a more simple net which could be used where the bottom was smoother.

The dredge could also be dragged behind the Challenger's steam pinnace.

The dredge could also be dragged behind the Challenger’s steam pinnace.

The specimens brought up would be sorted in the port-side natural history laboratory, which was equipped with microscopes and a wide variety of bottles, jars and spirits in which to preserve animals and invertebrates. Botanical specimens would be pressed and dried out in a warm area near the ship’s funnel (this was found to be far more efficient than using the purpose-built press that they brought with them!), and then everything would be catalogued and put into storage in the hold.

In the Natural History Laboratory, specimens could be examined and preserved with the use of scientific equipment. Note the microscope.

But it wasn’t just the living creatures that they were interested in. At one point, barometer and air temperature readings were taken every two hours for a whole year! At every station, the sea temperature was taken at various depths with a special pressure-resistant thermometer, and samples of the sea floor (using a Baillie’s sounder) and sea water at various depths (using a slip water bottle or a stopcock water bottle) were brought up for analysis. This was done in the starboard-side chemical laboratory. This was equipped with state-of-the art equipment for testing what gases were dissolved in the seawater, a glass-blowing bench and a hanging spirit lamp, designed to heat substances without spilling them in rougher seas.

This sounder was used to measure the depth of the ocean and collect samples from the seabed.

The doom and gloom of the HMS Challenger voyage…

The HMS Challenger voyage was massive. A four year long trip around the world is not going to go without ups and downs. Here are some of the sad and unfortunate deaths of the crew as the years went by.

18th November 1872 – Challenger at Sheerness, Kent

Let’s start right at the beginning. HMS Challenger started off in Sheerness to be refitted before going to Portsmouth. One dark night whilst still at Sheerness, a young man called Tom Tubbs was wandering up the ship’s gangway in the dark before tripping and drowning in the dock. Despite best efforts by shipmates and the police, poor Tom could not be saved. Could this have been a warning that the voyage would not go as smoothly as imagined?

25th March 1873 – Station 24a – Challenger between St Thomas and Bermuda

Early morning at 6.15am the ship got ready to sound and dredge. At 11.10am a dredge was put over but little did they know that when hauling in the dredge one of the hooks holding an iron block to the deck would break, sending the block flying and striking a young sailor, William Stokes, to his death. And it wouldn’t be much longer until tragedy struck yet again.

4th April 1873 – Challenger at Bermuda

Once the crew reached Bermuda they came across a beautiful picturesque harbour at Grassy Bay, not far from the capital of Bermuda. The atmosphere between the crew had just started to change for the better and so it must have been horrific for Richard Wyatt, the ship’s writer, to hear the dying gasps of the ship’s schoolmaster and find him dead due to a stroke. He was put to rest at a nearby cemetery in Bermuda.

28th June 1874 – Challenger on route to New Zealand

The next death recorded was some time after Bermuda. On route to New Zealand, nearly at the harbour, Edward Winton was out to do a sounding when the sounding cable got caught. He went to free it from the anchor when a huge wave of water struck the ship, knocking poor Edward into the sea, never to be found.

13th September 1875 – Challenger on route to Tahiti

Dr Rudolph von Willemoes Suhm, born September 11th 1847, joined the Challenger at the age of 25 as a naturalist. Moseley was very fond of him – learning a lot from his knowledge and proud of his enthusiasm for zoology. Sadly, Suhm got erysipelas, a bacterial infection that attacks the skin and died at the age of 28. It was a sad time for all.

23rd January 1876 – Challenger at the Falklands

Nearing the end of their journey, despite being very happy to be on the Falklands and drinking to celebrate, a young sailor fell overboard. This young man was popular amongst all and was planned to be married when the voyage was over.

So there we have it – and there were probably far more deaths that aren’t recorded as well as illnesses and disease that riddled some of the crew. There are also some stories in the diaries that give us an insight into the world of the locals too. In Fiji, when highly regarded visitors went to see the great chief, the visitor had to bring human flesh, usually of a prisoner, just for fun. If there were no prisoners the visitor had to go out and find others to kill for the chief – usually a lone girl or woman. Horrible to believe how some people used to live!

Project update

Regarding the Challenger project, I had a successful Scotland visit – seeing the Hunterian in Glasgow and the collection centre at NMS, taking lots of photographs for the database. Great fun and such a lovely bunch of people! Holly has also had a great trip to Manchester. Just another few months before the database goes live! To help us with this, we welcome our new volunteer, Peter, to the Challenger team! Here he talks a little bit about himself and his interests in the project:

“I am a history student at the University of Exeter. This project is interesting to me because, as a student, I very much appreciate it when online archives I use in my research are well organised and easy to access. This will be a great insight into how the archiving process works. As a tech enthusiast I am always interested to see my degree and my interests used together to help our knowledge of the past. Now that my exams are done I look forward to getting involved behind the scenes at this great museum!”

April’s Anemones

April’s anemones!

Sea anenomes are in the phylum cnidaria, like jellyfish. Sea anemones attach themselves to rocks with their adhesive foot, attacking prey as they go past with their stinging tentacles. Their tentacles have cells that contain toxins that, when touched, shoot out venom that paralyse the prey. The anemone then uses its tentacles to bring the prey into its mouth.

With over 1000 species of sea anemone, they range from 1/2 inch across to 6ft!  They can be found all over the oceans.

On the HMS Challenger expedition, several species of sea anemone were dredged and trawled. Take a look at some of the plates found in the reports below..


Plate 1 from the Challenger Actiniaria report. Showing genera such as Porponia, Cercus and Paractis.


Plate 2 from the Challenger Actiniaria report. Showing genera such as Corallimorphis, Polysiphonia and Bunodes


Plate 3 from the Challenger Actiniaria report. Showing genera such as Stephanactis, Amphianthus and Ophiodiscus

One species of anemone found on the expedition was Calliactis polypus. They were found on station 208 on January 17th 1875 at 18 fathoms and also at St Vincent, Cape Verde. They were all found on gastropod shells that hermit crabs were living in. This is because the anemone gets to live and feed on the shells in return for protecting the crab. The anemone isn’t naturally attracted to the shells but the hermit crab will persuade the anemone to fix itself on to the shell by tapping on the shell so the anemone relaxes.

Project update!

We are moving a long at a nice pace with the Challenger Project – with the help of many museums we are starting to collect a large amount of Challenger material which I am currently sorting to go on our database. If all deadlines are stuck to, the website/database should go live at the end of September this year. Keep  your eyes peeled!

In next month’s blog I will be reading up on the narratives and diaries of HMS Challenger and will be looking in to the dark side of the voyage where all was not going well..

March’s Molluscs

March’s Molluscs!


Today I will tell you about some of the molluscs found on the Challenger expedition along the way – more specifically, the octopus (read about January’s jellyfish here). Above are pictures of cuttlefish and octopus found on the expedition.

Firstly – what are molluscs? These are a very large phylum of invertebrates with about 100,000 species! They are soft-bodied animals, some with shells (such as snails and scallops) and some without (such as slugs, octopus and squid). There are quite a few classes of molluscs but I won’t go through them all – the octopus belongs to the Cephalopods.


So let’s get started with the octopus. These are fascinating creatures. There is one species of octopus known as the ‘mimic octopus’. This is because it can make itself appear to be many other sea creatures! There is another octopus which is known as the ‘hardest working mum of the planet’. The mothers guard their eggs, protecting them from predators and keeping them oxygenated. Unfortunately, this means that the mother never leaves their side to even eat. Many die very soon after their young hatch. This particular octopus though, Graneledone boreopacifica, has been found to guard its young for 53 months! The most well-known octopus is Octopus vulgaris – also known as the common octopus. This may seem a little boring but these well-studied creatures are still pretty amazing. It has recently been found that these clever octopus’ can recognise ones that they have previously seen in the past day.


The big blue octopus (now Octopus cyanea)

Many octopus’ were found on the HMS Challenger expedition – Octopus cyanea (the big blue octopus) and  Enteroctopus dofleini (the giant Pacific octopus) to name two. The giant Pacific octopus is one of the largest octopuses and  they can also live the longest. The largest recorded has grown up to 30 feet and weighed over 270kg! They are very intelligent – like the mimic octopuses and the big blue octopus, they can change colour to match their surroundings due to their skin pigments.  They have also be known to solve maze puzzles in the laboratory and recognise individual human beings! The giant Pacific Challenger specimen was found at station 232, off of Japan on May 12th 1875 and the big blue octopus was found by the Hawaiin Islands in August 1875.

The crew on the HMS Challenger pulled up many species that have not been often seen since. The species of octopus in the image below was found on route from New Zealand to Indonesia (stations 171 and 214) and so few have been found, it is down as data deficient on the IUCN red list (showing the abundance of species and change in numbers over time). This shows how extensive the work was that the crew on HMS Challenger did!


Grimpoteuthis meangensis (Hoyle, 1885)

Keep your eyes peeled for April’s Anemones!

January’s Jellyfish

Hello and Happy New Year to you all!

January’s jellyfish! For this month’s post I am going to tell you about two species of the jellyfish found around the seas from the HMS Challenger expedition. They are named differently now but after a bit of research we found out what their current names/species are.

Carybdea murrayana

Carybdea murrayana

Let’s start with the genus Carybdea – the jellyfish belonging to this genus are known as box jellyfish – you don’t want to mess with these! They are highly venomous and their sting attacks the heart and nervous system, which can instantly kill prey. These jellyfish have tentacles from each corner of their bell, each one with about 5000 stinging cells.


Carybdea murrayana

Carybdea murrayana

The two females found by the Challenger (Charybdea murrayana, now Carybdea murrayana) were found on April 9th 1876 at station 348, off the West Coast of Africa, not far from Sierra Leone. An interesting fact about box jellyfish is that they have ‘true’ eyes (as well as simple eyes). The simple eyes just detect light but the ‘true’ eyes have a retina, lense and cornea. It has been shown that these are used to help navigate by looking upwards to the mangrove canopies. This is where they usually feed and by detecting the canopies they stay underneath them to ensure they don’t stray too far from home. If cover is removed, they have no sense of orientation.

Carybdea murrayana

Ptchogastria polaris

Next up we have the genus Ptychogastria. These don’t have a common name and only one of these jellyfish was found on the expedition. These attractive jellyfish are from the order Trachymedusae. A lot of jellyfish have two body forms – polyp (stationary) and medusa (free-swimming). However, this order of jellyfish just grows in to the medusa stage. Although they grow only into the free-swimming form, they have suckers to attach themselves to rocks, waiting for prey to pass so they can reach out their tentacles to capture them. So they don’t swim that much after all! The one Ptychogastria jellyfish found was from station 50 – on the 21st May 1873 near Halifax, off the east of Canada. It was then identified as Pectyllis arctica but has since been updated to Ptychogastria polaris.

Christmas Day on the HMS Challenger

Christmas  on HMS Challenger

Hello again! Since it is that time of year when the Christmas tree is decorated and soon you will be tucking in to a massive Christmas dinner, I thought you would be interested to know what Christmas was like on board the Challenger. Four Christmas’s were spent out at sea or anchored up and according to the HMS Challenger narrative and diaries this is what went on:

Christmas 1872 on board the HMS Challenger


Challenger set sail on 21st December 1872, just in time for Christmas.  142 years ago from the day this post was published! Unfortunately, Christmas this year was a bit of a miserable one weather-wise. It was very windy, with the crew having to hold tight to their food dishes – many were lost and some food jars, in particular jam and pickles, got smashed on the floor. However, with ham for breakfast and meat pie and plum pudding for dinner the food went down quite well. Every member on the ship was given a third of a pint of sherry too. The officers weren’t so lucky with their food though. The turkey was stolen and they never found out who it was.

Christmas  1873 on board the HMS Challenger

The HMS Challenger spent the second Christmas off Prince Edward Island – belonging to South Africa. Again, the sea was very rough. At about 10am,  the crew caught sight of land but they weren’t due to anchor until Boxing Day. Dinner this year was salt pork and pea soup, plum pudding and a third pint of madeira for each man so quite enjoyable, with music and dancing for entertainment. The men were thinking about where they were going to be the following years at Christmas – around Hong Kong in 74 and near Valparaiso in 75.

When the men anchored on Boxing Day and explored the island they saw many birds – cormorants, albatross,  skua, gulls,  a giant petrel, prion and a sheathbill. This was on top  on three different penguins. One of these was the Gentoo penguin. This penguin is nearly as big as the King Penguin, which was also found on the island. The third of the penguins was the rockhopper penguin, who had very dirty looking nests. Have a look at their photograph of the albatross nests below.


Christmas 1874 on board the HMS Challenger

Indeed, the ship was in China over Christmas in 1874. They arrived in Hong Kong on 16th November 1874 and stayed there until the beginning of January. Christmas here was lovely and warm – nothing like the cold and wet weather of the previous years. A fine dinner with turkeys, geese, ham and of course the plum pudding was devoured by all. Members of the crew save money each month for when they are at land to treat themselves. In Hong Kong they often ate curried cats and dogs..a delicacy there at the time apparently!

Christmas 1875 on board the HMS Challenger

The final Christmas on board! The men were once again correct in 1873 – they had just left Valparaiso on the 10th December. Unfortunately six men were lost there from leaving without consent. Christmas Eve brought music and dancing with a band and many stage acts which was great fun for the men. It was a cold Christmas day at sea this year. Dinner this year was a fat bullock to keep them going. Of course we can’t forget about the plum puddings! Christmas was very enjoyable until the evening. Many of the seamen managed to smuggle in multiple bottles of alcohol, leaving many drunk and fighting terribly. One man even came away with a broken jaw in three places! So it didn’t turn out terribly well in the end but it was all self inflicted!

So those are the main details we have about Christmas on HMS Challenger – food, drink, music, dancing, a mix of weather and the occasional fights (what’s changed?!). Seriously though, life wasn’t easy – I’m sure those men were relieved to have their next Christmas on land with family where they belong.

Have a happy Christmas and New Year everyone!

Letters written and data recorded from the HMS Challenger

Station recordings from HMS Challenger

Here we are again! I told you all last time I would let you see some of the original data from the reports from the HMS Challenger. Let’s look at some recordings from station 256. This was on the journey from Yokohama to the Sandwich Islands on July 21st 1875.




As you can see they measured:

  • Date and times
  • Longitude
  • Latitude
  • Air temperature
  • Water temperature at different depths
  • Density
  • What they found deposited at the bottom
  • Amount of carbonic acid in the water
  • The water current
  • Species found






They even went in to detail about an albatross having a cotton handkerchief around its neck. They certainly gave very detailed accounts of what they found. The material and species found were sent to scientists around the world once the expedition had finished, allowing them to be identified and written in the reports.


The letters and diary of Joseph Matkin


(Photograph and quotes from: Philip F Rehbock, 1992.  
At Sea with the Scientifics: The Challenger Letters of Joseph Matkin. 
University of Hawaii Press).

There were letters and diaries written by members of the crew and some of these have been documented. Joseph Matkin, only 19 when the voyage began, was a member of the crew aboard Challenger and was a ship’s steward’s assistant for the whole voyage. He wrote a journal throughout which gives a different and more personal perspective of the voyage to the scientists. He speaks of food the crew ate, the people they met on land, the weather and also deaths that occurred along the way. Here are some quotes from a book published containing his diary and letters.

February 9th, 1873 “Last night one of the men caught a shark, about 6 feet in length…he was lively as ever..The old gentleman is now being eaten for dinner in the mess of the men who caught him”
June 28th, 1874 “The deceased Edw Winton was one of the finest and steadiest seamen in the ship, was about 25 years old, & married just before we left England…no one knows whether he was stunned against the ship’s side by the sea, or he might have been struck by the fans of the screw as he drifted under the stern.”
February 24th, 1875 “The natives are undoubtedly lazy, but the Spaniards do very little but smoke, drink coffee and fan themselves, the only hard workers in the Philippine islands are the Chinese.”
July 27th, 1875 “The island of Oahu has a very pleasant rural appearance…the weather is much hotter here; Thermometer 85° in the shade, and over 120° in the sun. The ship is already full of flies,& the ravenous but playful Mosquitos are only waiting for us to turn in before commencing their onslaught.”

The writing is fascinating and his language shows that he was obviously quite a well-educated man. I recommend having a read of these letters if you are interested in a more personal view of the voyage.

Will write again soon!
