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...

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...

Healthy cold-water corals in the Western Darwin Mounds
As explained in the previous blog post, the Western Darwin Mounds host a more pristine ecosystem than the Eastern Darwin Mounds. Historically, less bottom-trawling activity was reported in that area before the fisheries closure was put in place. On Tuesday 16th and Wednesday 17th of September, we...

Scientific eqipment recovered after 8 years covered in fauna
On the 13th of September, just before the stormy weather came in, the first survey Autosub6000, our AUV (Autonomous Underwater Vehicle: a robotic submarine that can be programmed to scan the seabed with a side-scan sonar for 24 hours, without pilot supervision), was completed. The sonar maps the...

On the morning of the 11th of September the Royal Research Ship Discovery arrived at the western Darwin Mounds. The weather allowed us to collect data using a variety of techniques. The seabed substrate from ±1000m depth was sampled using a box core in order to characterise the fauna (under 1mm)...

A healthy coral mount.
On Friday 6 September a team of scientists and engineers, led by the National Oceanography Centre (NOC) and University of Southampton, will set sail to revisit a deep, cold-water coral reef area 16 years after it was named a Marine Protected Area, to look for evidence the coral is regenerating....

RRS Discovery on way to the Darwin Mounds
Earlier today, the Royal Research Ship (RRS) Discovery departed from the National Oceanography Centre (Southampton) to bring a team of 20 scientists to revisit the Darwin Mounds marine protected area. This marine protected area is named after the RRS Charles Darwin, the research vessel from which...
