Porcupine Abyssal Plain expedition blog

The RRS James Cook is off to the Porcupine Abyssal Plain in the North Atlantic to recover data from an observatory moored there. The PAP site is located in 4000 metres of Atlantic Ocean, southwest of Ireland. It is an important permanent site for deep ocean research.

The scientists will be recovering a suite of moorings that was deployed a year ago at the PAP site, and then redeploy new moorings.  The moorings carry sensors to record sea temperature, nutrients, productivity and meteorological variables all year round, but the in-depth studies which will be carried on over the next few days will be used to add extra value to the mooring data, as well as answer specific scientific questions. Samples will be taken of the sediments in the seabed, microbes will be counted and nets deployed to look at slightly larger fauna, and all the samples taken will be processed, and some analysed. This blog will explore some of the research that goes on during an expedition.

Maureen Pagnani: how I got to be at 16 degrees W, 49.5 degrees NMaureen Pagnani

I have been working with the PAP data since 2002, processing numbers, plotting graphs and creating the web sites. At NOC I am a data manager, and so as with most people lucky enough to be on this cruise I have several roles. As well as documenting many of the activities in video and in still photos I am making sure that all the work we do is documented and all the metadata (data about data) is recorded. These are such things as the exact latitude and longitude, water depth and time that each activity takes place. This will ensure that the data collected will be of value to any and all scientists in the future.

Blogging from the Southern Ocean

The RRS James Cook is in the Southern Ocean on a 51-day expedition to look at deep water mixing in this turbulent ocean. Two young scientists aboard, Alex Brearley and Katy Sheen, are running an expedition blog from the ship at: dimesuk3.blogspot.com

Information for…


The outputs of research generate new knowledge about the oceans. Transferring scientific knowledge to support business and industry is an important part of our NOC remit.



Our research is intended to tackle the big environmental issues facing the world. Research priorities will include the oceans' role in climate change, sea level change and the future of the Arctic Ocean.



The University of Southampton and the University of Liverpool both offer a range of highly regarded undergraduate and post-graduate degrees in Ocean and Earth Science.



For any media or press enquiries to the National Oceanography Centre follow the more link below. Please note the centre's press office is staffed from 0830 to 1730, Monday to Friday.
