Blue Planet 2 | Episode 6 | Coasts

We have a tendency to take our coastlines for granted. It is by far the most accessible and relatable marine habitat, with thousands flocking there every day for their primary source of food, watersports, or just to relax. The UN estimates 40% of the world's population live in coastal areas. They provide the most extensive economic and social benefits of any natural habitat, encompassing 77% of the services provided to us by all ecosystems. Continue reading →

Blue Planet | Episode 4 | Big Blue

The open ocean may seem like a vast, featureless wasteland to us outsiders, but its inhabits are intrepid navigators that use its structures to embark on some of the most epic journeys known to science. Leatherback turtles have been shown to migrate across the entire Pacific Ocean. Two hatchling leatherbacks were once tracked moving 39km in 34 hours and 82km in 39 hours, an extraordinary distance for a baby weighing less than 40g in one of the first days of its life.

In a Sea of Stars

                  Today's guest blog post is from my good friend and office mate Christina Wood. Christina will tell you all about herself and the work she does, take it away Christina... I am a PhD student studying at the National Oceanography Centre in Southampton, UK. In March 2017, I participated in a cruise to the Barents Sea to assist researchers as part of the ongoing MAREANO project. Continue reading →

Why getting dirty is good for all of us

Darwin extolled the virtues and dedicated his last works to it, few places on Earth are without it, and there is little doubt that human well-being benefits tremendously from it, but what is bioturbation?   It is sobering to think that at any time of day or night an army of invertebrates actively modify the soils and sediments beneath our feet, something that they have been doing for millions of years and which most people take for granted.

Limpets – My Favourite!

People often ask "So what do you work on?" and pre 2012 whenever I replied "On Limpets" they would get very excited and say "What the OYLIMPICS!!!" and I would then get a barrage of questions about how to acquire tickets!!! Thankfully since London 2012 that's all calmed down a bit. My lovely limpy, limpy do da's - that's the limpet song which can be heard being sung on rocky shores up and down the country by people dressed in rubber! Its a glamorous  job. Continue reading →

Polar marine biology

This week the course focused on marine life. How diverse, abundant and adaptable it is. However, there is one region where life has to deal with extra challenges. A changing light system, from 24 hours of sunlight to complete darkness for months, harsh sub-zero conditions and changes to the composition of seawater from the freezing and thawing of ice. This is of course the Polar Regions (Arctic in the north and the Antarctic in the south). Continue reading →

Emma Cavan: How did I become involved in Ocean Sciences?

I am currently doing a PhD in the ocean carbon cycle however my aspirations at 16 were somewhat different! I grew up in a house of medics and this limited my career pathway knowledge and hence I applied for degrees in medicine. I was quickly rejected from most of the universities I applied to and to this day I am incredibly grateful! It was clear medicine wasn’t something I was passionate about but I knew I didn’t want an office job and so biology seemed the obvious choice. Continue reading →
