CASIX held their final science meeting at the Geological Society in London on 2nd July 2008. The meeting entitled "Uncertainties of the Ocean Carbon Cycle: understanding changes in fluxes and ecosystems" presented latest results from the CASIX five-year programme to a mixed audience of scientists and policy makers. The meeting concluded with a discussion on how ocean carbon cycle research can be better used to guide and inform policy. A report of the meeting will follow shortly and for further information and presentations please click here.
01 April 2008
The National Centre for Earth Observation (NCEO) was commenced its research programme today. This new NERC centre is the successor to the NERC Centre of Excellence in Earth Observation programme and will seek to build on the success of CASIX and the other Centres. NCEO is headed up by Prof. Alan O'Neill from the University of Reading as Director. The research is organised around 8 research themes: climate, carbon cycle, atmospheric composition, hazardous weather, cryosphere, dynamic earth, data assimilation and EO informatics. The carbon cycle theme will build upon CASIX advances in the areas of air-sea fluxes, phytoplankton community structure and primary production, bio-physical interactions, data assimilation and model reanalysis.
31 March 2008
Having succesfully led CASIX through its five-year funding phase, Prof. Jim Aiken has decided to retire (for the second time!). Dr Nick Hardman-Mountford will take up the reigns as Acting Director until completion of the CASIX project later this year. Prof. Aiken has been the driving force behind CASIX and many other intitiatives in marine science over the past 38 years, most notably the Atlantic Meridional Transect programme, the Undulating Oceanographic Recorder and the development of ocean colour satellite research in the UK. He is looking forward to spending more time on the golf course (although we can't keep him away from the office still!).
21 February 2008
A one day scientific meeting was held to celebrate the research career of CASIX Director Prof. Jim Aiken. The meeting "Illuminating Ocean Ecosystems" focused on bio-optics of the ocean carbon cycle and was held in Plymouth on 19th February 2008. For presentations and images from the day please click here.
21 January 2008
CASIX has received 2 PhD studentships from the NERC algorithm allocation for 2008. Details of topics can be found on the Studentships page.
20 December 2008
The CASIX Annual Science Meeting was held in Exeter from 17-18 December 2007, hosted by the Met Office. The meeting commenced with talks by final year students on "Convective gas exchange in the tropical Atlantic" (Chris Jeffrey, Southampton), "Novel techniques to estimate primary production" (Kathryn Barker, Plymouth) and "Remote sensing of chlorophyll concentrations in turbid waters" (Elizabeth Kyte, Bangor), followed by some shorter presentations and posters by Vivian Scott (Edinburgh), Elizabeth Jones (UEA), Rhian Evans (Leicester), Diane Knappett (Leicester) and Bob Brewin (Plymouth). David McKee, a CASIX-affiliated NERC research fellow at the University of Strathclyde, talked on advances in bio-optics.
The evening commenced with a drinks reception and Oxford Union-style debate with Jim Aiken (PML) proposing the motion "The Oceans are the heart and lungs of the global C-cycle and the Earth’s climate system", seconded by Nick Hardman-Mountford (PML). The motion was opposed by Peter Cox (Exeter), who spoke in favour of the terrestrial biosphere, seconded by Chris Merchant (Edinburgh) and contributions were also made from the floor. The final result was declared a draw and we adjourned for a CASIX Christmas dinner.
The following day commenced with a keynote address by Andrew Watson (UEA) on "Current state of knowledge of the Ocean Carbon Cycle", which highlighted the need for sustained funding of in situ observations. This was followed by updates of progress in the main science themes.
22 October 2007
Further evidence for the decline of the oceans' historical role as an important sink for atmospheric carbon dioxide is supplied by new research by environmental scientists from the University of East Anglia, which includes Prof. Andrew Watson, a CASIX Principle Investigator.
Since the industrial revolution, much of the CO2 we have released into the atmosphere has been taken up by the world’s oceans which act as a strong ‘sink’ for the emissions. This has slowed climate change. Without this uptake, CO2 levels would have risen much faster and the climate would be warming more rapidly.
Results of their decade-long study in the North Atlantic show that the
uptake in this ocean, which is the most intense sink for atmospheric CO2,
slowed down dramatically between the mid-nineties and the early 2000s.
3 October 2007
Three new CASIX PhD students have started their projects this month. Emmer Litt will be based at University of Wales and Plymouth Marine Laboratory (PML), working on the seasonal cycle of pCO2 in Northwest European shelf waters.
Bob Brewin will be based at the University of Plymouth and working with PML and the UK Met Office on the relative contribution of different phytoplankton groups to air-sea CO2 exchange.
Diane Knappett will be based at the University of Leicester, working on the retrieval of atmospheric methane concentrations over the ocean using satellite measurements.
28 September 2007

CASIX collaborator is awarded NERC Fellowship
2nd October 2006
From 1 October 2006, Helen Kettle from Edinburgh University will begin a NERC Fellowship to continue the development of a 1-d marine ecosystem ocean turbulence model, with a Lagrangian model for phytoplankton acclimation, coupled to a bio-optical model. The aim is to provide a forward model for water leaving radiance so that ocean colour (satellite) data can be related to the state of the marine ecosystem. This will contribute to quantification of the global carbon cycle and aid climate change prediction.
Previously Helen has been working on CASIX P8 (1-D modelling) and will continue to collaborate with CASIX in her new role.
6 July 2006
An expert panel convened by BBC News, including CASIX investigator Prof. Andrew Watson (UEA), has concluded that climate change is "real and dangerous". The panel's discussions were based on themes set by Professor James Lovelock in his latest book The Revenge of Gaia.
Temperatures are likely to rise by 3oC to 5oC by the end of the century, with impacts likely to be "severe" but not "catastrophic", the panel said. It also concluded that politicians are unlikely to cut emissions sufficiently to prevent dangerous global heating.
The full story and results of the panel can be found from the following links:
14 April 2006
The Global Climate Observing System (GCOS) is preparing a supplemental document that provides detail to the requirements of the Implementation Plan for the Global Observing System for Climate in Support of the UNFCCC ("GCOS Implementation Plan", GCOS-92, October 2004) for satellite-based climate products and datasets that need to be available to all Parties to the UNFCCC (UN Framework Convention on Climate Change). This document is intended to assist Parties (countries) that support and/or use Earth observation from space in working with their Space Agencies to respond to the requirements of the GCOS Implementation Plan. This document covers a wide range of topics and issues which need community advice and consultation in its preparation.
An initial draft has been prepared by a group of authors from the climate community, in collaboration with the GCOS panel chairmen, and is now available for review and comment on the GCOS homepage: http://www.wmo.int/web/gcos. Comments should be sent electronically to email@example.com. The period for open review and comment will last from 14 April to 12 June 2006. This report will be published by GCOS in September 2006.

Royal Society report on ocean acidification from increasing atmospheric CO2
30 June 2005
The Royal Society has today launched its report on ocean acidification due to increasing atmospheric carbon dioxide. Drawing on the knowledge and experience of the Royal Society's working group of international scientific experts, the report addresses the possible effects of increased carbon dioxide on organisms and ocean chemistry, and puts forward mitigation recommendations. PML's Dr Carol Turley, one of the members of the working group, explains that “oceans are becoming more acid because they are taking up carbon dioxide from the atmosphere due to emissions from human activities. It is happening now and will continue to do so. The impact on marine organisms and ecosystems is of great concern. This report on ocean acidification highlights a very strong argument to that of climate change for reducing our carbon dioxide emissions”. CASIX investigator Prof. Andrew Watson FRS (University of East Anglia) was a member of the Royal Society working group which conducted the study. Click here for the full copy of the report (PDF).
