Research Expeditions

At any one time scientists and technicians from the UK marine community can be at sea on numerous vessels. This page provides information on the current research expeditions being undertaken by our two Royal Research Ships Discovery and James Cook. Here you can discover where our ships are and what they are aiming to achieve.

 

Updates from the ships’ Plans of Intended Movement (PIM)

 

RRS Discovery RRS James Cook

Vessel: Discovery

DTG:    22117 0700L
Zone:   UTC

Subj:    PIM 
Exp No: JC155

Pos: 27 36.7N 017 08.4W
Co: Various
Spd: 4 Kts

Wind: Lt Airs
Sea: Calm seas

Weather: Fine and Clear 

Status: Fabric Maintenance ongoing, STBD lifeboat to be launched for trainng. Vessel will set onto Santa Cruz this evening to
conduct OPL boat transfer. Vessel will then move clear of Santa Cruz and conduct thruster test. Berthing Santa Cruz will be dependent on how
trails go. Provisional ETA AM 24th

VSAT - System has failed. Fault finding indicates that the issue is with the modem.
FBB being used for traffic, sending of attachments should be avoided, if they have to be sent then ensure these are small.

Controls over Ocean Mesopelagic Interior Carbon Storage - COMICS

The surface ocean is home to billions of microscopic plants called phytoplankton which produce organic matter in the surface ocean using sunlight and carbon dioxide. When they die they sink, taking this carbon into the deep ocean, where it is stored on timescales of hundreds to thousands of years, which helps keep our climate the way it is today.

The size of the effect they have on our climate is linked to how deep they sink before they dissolve - the deeper they sink, the more carbon is stored.  This sinking carbon also provides food to the animals living in the ocean's deep, dark 'twilight zone'.

Computer models can help us predict how future changes in greenhouse gas emissions might change this ocean carbon store.  Current models however struggle with making these predictions. This is partly because  until recently we haven't even been able to answer the basic question 'Is there enough food for all the animals living in the twilight zone?'. But in a breakthrough this year we used new technology and new theory to show that there is indeed enough food.

So now we can move on to asking what controls how deep the carbon sinks. There are lots of factors which might affect how deep the material sinks but at the moment we can't be sure which ones are important. We think that two important ones are the amount of surface biomass and the amount of oxygen inside the ocean.

In this project we will make oceanographic expeditions to two different places where only these factors vary to test how these different factors affect carbon storage in the deep ocean.

DY086 is the first of those expeditions. The second is to the South Atlantic just off South Africa in mid 2018. On both expeditions we will measure the carbon sinking into the twilight zone and the biological processes going on within it.

Then we will determine if the systems are balanced - in other words, what goes in, should come out again. We will then write equations linking all the parts of the system together and analyse them to make them more simple.

At the same time we will test whether the simple equations are still useful  by seeing if they produce good global maps of ocean properties for which we have lots of data.

Finally, when we are happy that our new equations are doing a good job we will use them in a computer model to predict the future store of carbon in the ocean and how it will change as the ocean warms.
