Anouska Panton – Discovery 361 – 10.04°N, 28.40°W

My name is Anouska Panton and I am a PhD student in the Nutrient Biogeochemistry lab at the University of Liverpool. My principal role on board is to collect and analyse dissolved oxygen bottle samples from both the stainless steel and the titanium rosette which will be used to…

Joe Snow – Discovery 361 – 2.00°N, 25.30°W

My name is Joe Snow and I started my PhD in Southampton last September. In the six months that I’ve been at NOCS my time has been spend familiarising myself with the background information for my project along with preparing for this cruise.

Preparing for your first cruise is a…

The ISW microstructure profiler

Alex Forryan – Discovery 361 – 3.10°S, 25.10°W

Turbulence measurements: On RSS Discovery cruise D361 turbulence in the upper ocean is being measured at every station using an ISW free-fall vertical microstructure profiler.

Turbulence is an energetic, eddying, diffusive, and highly dissipative…

David Honey – Discovery 361 – 0.10°N, 24.30°W

Hello, my name is David Honey and I’m a PhD student from the University of Southampton working onboard the RRS Discovery (D361). I’m in my final year of study and the results collected from this cruise are likely to feature heavily in my thesis. My work is primarily focused…

Elizabeth Sargent – Discovery 361 – 12.35°N, 22.00°W

Things are off to a great, albeit busy, start. We’ve worked up a good sampling plan, and have decided that we will normally do one station per day. A station can consist of a maximum of seven sampling events, such as deployments of conductance-temperature-density (CTD)…

Coring at night

We have videoed the many different areas of venting at the seafloor in the base of the Kemp Caldera and now are spending a cold, snowy night coring the mud from the seafloor. Our night shift work is to collect mud from around the areas of diffuse hydrothermal flow.

The Axe, Bransfield Strait

Our final site within the Strait is aptly named ‘The Axe’. This is the least studied site that we have chosen to study and first we need to map the seafloor.

Again we use the conductivity-temperature-depth package to identify anomalous chemical signals in the deep water over the volcanic ridge.…

Three Sisters, Bransfield Strait

We have spent the weekend surveying our second volcanic target in Bransfield Strait: the Middle of the Three Sisters. Again we use the plume sniffing approach followed by video surveys of the seafloor before choosing our coring sites.

Mud sampling: 28 January 2011

Alfred Aquilina and the sediment sampling team have been working hard in the cold temperature lab to extract water from the stinking mud from around the hydrothermal sites. “The most exciting thing is to see the data that we process on board” says Alfred, “we are really productive at sea; working…
