A team of scientists from across the country is studying how the ocean breathes. They are studying the exchange of gases, carbon dioxide and oxygen, in the Labrador Sea, one of the few places in the planet where water sinks deep into the ocean carrying these gases with it. The scientists are part of a team working on an NSERC funded CCAR project called VITALS – Ventilations Interactions and Transports Across the Labrador Sea http://knossos.eas.ualberta.ca/vitals/. They have put together a video to describe how the ocean breathes.
This research combines new observations and modelling to determine what controls the exchange of these gases and how they are linked to and interact with the climate system. This video explains how the deep ocean connects with the atmosphere and the role of this buy avodart online deep breathing in climate change. The leaders of this program are Paul Myers (University of Alberta), Roberta Hamme (University of Victoria), Jean-Eric Tremblay (Univesite Laval), Jaime Palter (University of Rhode Island),
Doug Wallace (Dalhousie University) and Brad deYoung (Memorial University.

Video series “Sea Level: A Liverpool View”
by Ric Williams, University of Liverpool
Part 1: Personal Perspective
Part 2: Historical Perspective
The video illustrates some of beginnings of sea level measurement, how the process has developed and considers what can be learned from taking a longer term perspective.
Part 3: Future Perspective?
The video considers why storm surges form and how sea level change in the future might contribute to increasing chances of coastal flooding.

Heather Furey (WHOI) and Mark Graham (UMiami) get the rosette ready for the first calibration cast of microcats and test of releases before Leg 2 moorings are deployed. Also on the package are the CTD (Conductivity-Temperature-Depth) sensors which relay water property values up a conducting cable as the package is lowered to near the sea floor.
