Marine Mammalogy Conference on the Biology of Marine Mammals 2015: San Fransisco

I would like to thank the Challenger Society for granting me a Travel Award which helped fund me to attend the 21st Biennial Conference on the Biology of Marine Mammals. The conference was a fantastic experience and it would not have been possible to attend without the Society’s generous support.

At the conference I presented a four minute speed talk entitled: ‘Heat shock protein gene expression in blubber of grey seal (Halichoerus grypus) pups during suckling and the post weaning fast: effects of development rather than contaminant exposure?’ during the Physiology session. This was my first oral presentation at a large international conference and it was an exciting, yet nerve wracking, experience. It was very beneficial to have the chance to present my research to a wider audience of scientists, outside of my supervisory team and institution, and also receive feedback. I was also able to support friends and colleagues during their own talks and poster sessions. I was happy to gain insight into the latest marine mammal research across a range of species and disciplines and, as I near the end of my PhD, consider potential collaborations with individuals and institutions whose work is similar to my own research interests.

I particularly enjoyed a talk in the ‘Health’ session by Dr Peter Cook (‘The neurobehavioral effects of naturally occurring domoic acid toxicosis in wild California sea lions’), whose work has shown that sea lions exposed to domoic acid had lesions in their hippocampus and exhibited reduced performance in spatial memory tasks; this could potentially lead to increased strandings and reduced body condition if foraging ability is compromised. There were many other enjoyable talks and posters in all sessions, including Ecology, Behaviour and the specific Sea Otter session.   

Additionally, I attended a workshop at the beginning of the conference, ‘Genomics Workshop II’, which though is not specifically my research field, there are important elements directly related to my research. For example, a presentation by a research group sequencing the Northern elephant seal (Mirounga angustirostris) genome was of particular interest as their published sequences are high quality and make it easier for me to design specific and functioning primers for my qRT-PCR (quantitative real-time PCR). The workshop also provided a good insight into choosing and using genomic techniques, and the different applications for genomics that are already being used to answer important questions in marine mammal biology.

I found that the conference was made up of friendly and interactive attendees and this provided a supportive atmosphere, which certainly catered for early career scientists. I came away from the conference having learnt new things, made some new friends and contacts, but just as importantly with a renewed enthusiasm for my own PhD techniques and data. 

Profile I completed my undergraduate degree in Marine Biology at the University of Portsmouth, and then went on to do an MSc in Applied Marine and Fisheries Ecology at the University of Aberdeen. My Honours project investigated the effect of PAHs (Polycyclic Aromatic Hydrocarbons) on the regeneration of the Sabellid worm Sabella pavonina, whilst my MSc research went in a different direction and focussed on the use of a bean protein concentrate (from faba beans) as an alternative protein source in feeds for commercially farmed Atlantic salmon (Salmo salar). I am currently at Plymouth University in the third year of my PhD which is entitled: ‘Eustress and distress in marine mammals: understanding the causes of cellular stress and the consequences for tissue function and whole animal health’. My focal species has been the grey seal (Halichoerus grypus) which has a fascinating physiology (e.g. female animals fasting during lactation). It has been a fantastic experience so far, with a mix of intensive field and laboratory work. I have spent a large amount of my time optimising the molecular and cell culture techniques that allow me to collect my data. The majority of my data so far has come from utilising qRT-PCR, investigating the gene expression of different stress markers (in particular heat shock proteins and antioxidants) in the blubber of suckling grey seal pups and lactating adult females.

Townhall on UK Arctic Ocean contribution to International Polar Year 32/33

 
SAVE THE DATE
12:00 11th June – 16:00 12th June 2025
NOC Southampton

The Arctic is one of the most rapidly-changing regions on our planet, with impacts on global sea-level rise, changes to our climate and weather patterns, and threats to our shared biodiversity and ecosystem services. With the international community rapidly mobilising towards the International Polar Year 32/33, and with new international programmes and initiatives now being shaped, it is timely for the UK Ocean Science community to come together and articulate what its unique offerings could be to Arctic research and technology.

This hybrid 2-day meeting, to be held at NOC Southampton, is intended to start this process. Recognising the Arctic Oceans role in global Earth and Human systems, anticipated outcomes include a high-level shaping of what the UK Arctic Ocean community would like to achieve over the course of the IPY, stimulation of new collaborations and proposals for grand Arctic challenges and a baseline from which wider integration with terrestrial, atmospheric and cryosphere communities, both in the UK and overseas, can be built.  Discussions will continue in diverse forums, including the UK Arctic Science Meeting in September and at Challenger 2026.

This action is supported by the UK Arctic Office and UK Arctic and Antarctic Partnership

Further details and meeting registration link will be circulated in April together with a questionnaire to help shape the agenda and discussion

Potential Availability of NERC Ship Time During the 25/26 Programme Year

The NERC Marine Facilities Programme for 2025/2026 for the RRS Discovery and the RRS James Cook has been published on the Marine Facilities Planning website.

The RRS Discovery programme currently contains a 79 day alongside slot between the 2nd of November 2025 and the 19th of January 2026, which is available for science delivery if funded science projects can make use of this time. Due to the location of the vessel, the ship is most likely to be able to deliver fieldwork in the North and East Atlantic regions. Some support for science capability within the National Marine Equipment Pool is potentially available, although there is no capacity for use of autonomous vehicles or remotely operated vehicles. Any fieldwork within Exclusive Economic Zones (EEZs) will need the appropriate diplomatic clearance submitted to coastal states at least 6 months in advance, and to NMF with sufficient lead time for processing via the FCDO.

If interested in making use of this ship time, please contact NERC Marine Planning (marineplanning@nerc.ukri.org) ASAP to start discussions.
