Data and Publications

As a world leader in marine science and research, we generate considerable quantities of data. We also produce a broad range of reports and other types of publication.

What data do we collect?

Cefas experts interpret data to provide UK government customers with the evidence needed to help secure sustainable blue growth, as well as meeting commitments to our food security and food safety.

Harmful Algal Blooms (HABS) Surveillance Programmes and Monitoring

At certain times of the year naturally occurring algae in the sea can give rise to blooms, which may not necessarily be noticeable. Algae in these blooms may produce potent biotoxins. These can accumulate in filter-feeding bivalve molluscs and sometimes in other shellfish, such as grazing gastropods.


Offshore Chemical Notification Scheme

Applies to chemicals that are intended for use and discharge in the exploration, exploitation and associated offshore processing of petroleum in the UK and Netherlands.

Sea temperature and salinity trends

We collect data on sea-surface temperature (and sometimes salinity) at a number of coastal sites around England and Wales.

Sanitary surveys

Sanitary surveys are an essential first step towards establishing a microbiological monitoring programme for the classification of bivalve production areas. All new bivalve production areas require a sanitary survey.

Shellfish classification and microbiological monitoring

Bivalve mollusc (shellfish) harvesting areas are classified according to the extent of microbial (faecal) contamination as shown by monitoring of E. coli in shellfish flesh. Treatment processes are stipulated according to the classification status of the area.

Shellfisheries water quality

We provide integrated policy advice, covering issues related to food quality and pollution impacts in coastal waters. The main focus of our advice is on the microbiological eaffects of human and animal pollution on commercially harvested bivalve molluscs (e.g. mussels, oysters, cockles, clams).
