Sampling at sea gives you many hurdles to overcome, and I am not just talking about seasickness! When we have a CTD rosette in the water it can be travelling through the water column for a few hours. The maximum rate of cable out is ~60 m/min, therefore in 6000 m depth this takes a minimum of 100...

By Hannelore Theetaert While I am writing this, it is 4o’clock in the morning, and it’s the start of the last two weeks of sailing.  CTD number 99 is currently going down to more than 5500m depth and the night-shift is up and running. In a few hours we will sample the niskin bottles, 10 or 20...

The International Day of Women and Girls in Science is a great opportunity to recognize the critical role women and girls play in science and technology. On board the RRS James Cook a team of 10 women explore the ocean characteristics through water sampling, analysis and data modelling. Dr. Maria...

We are reaching the end of week 2 of our 6 week Atlantic passage on the RRS James Cook, and what does this mean? Well, the whirlwind of the first few days are behind us, the night shift are slowly getting used to curry for breakfast and we’ve run out of marmite. Our food related issues aside...

When we think of a graveyard, the last thing that we think of is the ocean: a vast expanse of water that teems with life and a bounty of fascinating dynamical processes. The Gulf Stream happens to be a sink of highly energetic ocean processes, for example mesoscale ocean eddies. Eddies are...

Entire cruise track
The RRS James Cook departed from Fort Lauderdale (Florida, USA) to Tenerife (Spain) in the early morning of the 19th of January 2020. With it, the JC191 expedition began its goal of completing a full depth hydrographic section in the subtropical North Atlantic Ocean. Picture 1. Entire cruise track...

Sailing home
On the 25th of September, early in the morning, HyBIS completed her last dive at the Darwin Mounds. Later on, the Autosub6000 was recovered after a 24-hour survey. After completing some further CTD work for colleagues in NOC, the RRS Discovery is now heading home. During more than two weeks, we...

Abundant cold-water coral thickets in the 'pocket mounds'
We know that the Darwin Mounds are a unique and diverse place, but the site is large, and there are still areas that we know very little about. One of these areas explored during our expedition is known as the ‘pocket mounds’, just north of the eastern Darwin Mounds field (named like this because...

Image of whale carcass mapped by BioCam at 950m depth
As we mentioned in our previous post, the Autosub6000 Autonomous Underwater Vehicle (AUV for short) was launched from the RRS Discovery to map the seafloor. What you may not know is that this survey is following a totally different approach when it comes to seabed mapping. The team behind this...

Studying xenophyophores and macrofauna from boxcores
After the success with our first AutoSUB6000 survey around the Darwin Mounds, the AUV was deployed for the second time and our team of scientists from the sister project BioCAM are extremely excited to see all the data it has been collecting during its surveys. In every dive, our scientists aim to...
