What does the ocean mean to me?

Growing up near the Jurassic Coast means the sea features quite frequently in childhood memories. We are very lucky in the UK that for the most part you are never very far away from a coastline. Coastlines represent a striking physical example of how powerful and dynamic the oceans are and provide a continually changing yet persistently important environment. Continue reading →

Hi There!!

I’m Dr Josh Allin, a marine geoscientist and former PhD student at the National Oceanography Centre, University of Southampton. My research focusses on the processes that transport sediment within the world’s oceans, particularly submarine landslides and turbidity currents. Submarine landslides and turbidity currents are one of the most voluminous sediment transport mechanisms operating on our planet. They are also the principal mechanisms transporting sediment into the deep ocean. Continue reading →

What does the ocean mean to me: Josh Allin

Hi everyone Given that your first task is to give us examples of images which you feel best represent the oceans, here are a few which I feel highlight their significance. 1. Cliffs of Moher, Ireland Few places give us a more spectacular view of the influence of the oceans on Earth. Over millions of years they shape the continents through the processes of erosion and deposition, redefining landmasses and providing one of the most important environments we have – Coastlines. 2.

Welcome to “Exploring our Oceans” 5.0

Dear all   Welcome to the fifth run of the University of Southampton MOOC "Exploring our Oceans". The course starts on the 23rd January, 2017 and the team is looking forward to welcoming a new group of learners. We have collated the feedback from previous runs of this course into the image above, and hope that this run of the MOOC will help answer some questions about the ocean, and develop your understanding of the complex issues affecting our oceans.

How can I get involved?

As we come to the end of the MOOC, perhaps you are wondering how you can help to protect our seas and get involved with ocean science. First and foremost, take a few simple steps to minimise the effect YOU have on the oceans – there’s a great list of simple things you can do (and avoid doing!) here: http://www.wildlifetrusts.

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 →

Tracing Metals

Tracing metals I love the ocean, studying it, and before joining the University of Southampton as a Research fellow, I had put much thought into the particular role of shelf seas in the global marine system. In previous years I have put my focus on the deep ocean. I have been analysing trace metals in seawater to look at the big picture – how water masses with billions of liters per second are distributed along the ocean conveyor belt. Continue reading →
