Recently colleagues from the Sir Alister Hardy Foundation for Ocean Science (SAHFOS) were on board MBA Sepia to test a new piece of equipment, the ‘ocean indicator’. MBA Sepia assisted in the testing of the ocean indicator, towing the device at different speeds that it would experience during its maiden voyage. The deployment, recovery and behaviour of the instrument was recorded by SAHFOS and the crew of the MBA Sepia over two days, contributing to its successful launch in August 2017.
The ‘ocean indicator’ is a far smaller version of SAHFOS' Continuous Plankton Recorder, and has been provided to the all-female crew of the yacht undertaking the Exxpedition around the UK . The yacht will be towing the indicator to investigate the amount of microplastics found in the ocean.
Post-Doctorate Research Assistant Dr Clare Ostle said: “ The...

A new paper published in the Proceedings of The Royal Society B
Community responses to seawater warming are conserved across diverse biological groupings and taxonomic resolutions
Scientific Abstract : Temperature variability is a major driver of ecological pattern, with recent changes in average and extreme temperatures having significant impacts on populations, communities and ecosystems. In the marine realm, very few experiments have manipulated temperature in situ , and current understanding of temperature effects on community dynamics is limited. We developed new technology for precise seawater temperature control to examine warming effects on communities of bacteria, microbial eukaryotes (protists) and metazoans. Despite highly contrasting phylogenies, size spectra and diversity levels,...

Amphipods are small, shrimp-like invertebrates, and members of the sub-phylum Crustacea that includes crabs, lobsters and barnacles.
What is the difference between sea fleas and sea lice?
Sea fleas have been in the news recently. Common names often vary from area to area and what are known as “sea fleas” in Australia are called “sand hoppers” in the UK (e.g. the sand hopper Talitrus saltator see more at http://www.marlin.ac.uk/species/detail/1820 )
Sea fleas/sand hoppers are amphipod crustaceans. There are many species, mostly marine but also some that live in freshwater and some that are terrestrial. See our YouTube video for an introduction to amphipods.
We use the term “sea lice” for parasitic copepods, best known for being parasites of salmon (and a problem for salmon farms). However, in other...

A major assessment of climate change impacts on the UK marine environment over the past decade is released today.
Furthermore, the importance of the 2017 Marine Climate Change Impact Partnership (MCCIP) report card, which examines what was reported in 2006 and how this has changed for key topic areas over the past 10 years, has been recognized by Sir David Attenborough. He said: " Concern about the state of our seas has caused them to be studied more intensively – and extensively – than ever before. Here is a summary of the findings. They have never been more important. "
The Partnership brings together scientists, government, its agencies and NGOs to provide co-ordinated advice on climate change impacts and adaptation around our coast and in our seas.
The 2017 report card has also provided lessons for science to policy reporting. The MBA's Dr Matt...

Scientists from Plymouth are warning the UK kelp biofuel industry to beware of viruses. Whilst known to infect certain types of seaweed, a new study published in the ISME Journal is the first to describe viruses in kelps, which are important both ecologically and commercially.
Researchers from the Marine Biological Association (MBA) and University of Plymouth examined Laminaria and Saccharina kelps commonly occurring around the British Isles, and which include target species for the emerging kelp biofuel industry. They detected viruses by searching at the molecular level for their DNA 'fingerprint', and their presence was confirmed by observation of symptoms of infection using conventional and electron microscopy.
Kelps are the largest brown seaweeds, engineering temperate rocky coastlines into complex habitats comparable to terrestrial forests,...

The UK Marine Climate Change Impacts Partnership’s report on 10 years of science to policy reporting on the impacts of climate change made media headlines nationally and internationally. The Marine Biological Association’s Dr Matt Frost did a number of interviews in response to interest in issues such as changes in UK fish and bird populations. The fact that the project has involved hundreds of scientists and been running for over 10 years adds a significant weight to the evidence being presented – perhaps the reason that the media has taken particular interest in this story.
