Mesocosms; environmental laboratories

Studying the biology of the marine environment can prove tricky, there are many factors you must consider when looking at it. The influence of water chemistry, physics, weather can all impact the biology. We can work in the laboratory, and control a number of these. We can determine how much light or nutrients organisms get, which allows us to test specific variables. But there is an “in between” of the lab and the environment, and this is what is known as a mesocosm. Continue reading →

I am a Palaeoceanographer

As a palaeoceanographer most of the samples I work on have been collected during ocean drilling expeditions by the International Ocean Discovery Program (or DSDP/ODP, IODP’s predecessors). This vital program brings together scientists from all around the world to work together to tackle the big remaining unanswered science questions about our oceans and Earth’s history.

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 →

Tiny grazers love to eat their greens

This blog is from a mesocosm experiment (giant (5m by 8m deep) 'bags' placed into environments and filled with natural water) conducted during May 2017 (find more info here). It was written by myself & Sean Anderson (a graduate student at the Skidaway Institute, University of Georgia, USA). Members of the Harvey Lab get really excited about phytoplankton and for good reason. Continue reading →
