The changing oceans.
THE EVOLVING DISASTER OF THE GULF OF MEXICO OIL SPILL REMINDS US THAT OUR WELFARE depends on a healthy marine ecosystem and that the oceans are vulnerable to human activities. The oceans sustain a vast wealth of biological diversity, deliver critical ecosystem services, supply valuable natural resources, and are a central component of the climate system. It is therefore critical that the curren...
متن کاملConnectivity as a Management Tool for Coastal Ecosystems in Changing Oceans
Recent theoretical management research has focused on systems from species to ecosystem at large scales (i.e., metapopulations and meta-ecosystems), and the links between habitats patches and subpopulations are of crucial importance to understand, predict, and manage resource dynamics. One of the key characteristics affecting the dynamics and demography of metapopulations is thus connectivity (...
متن کاملSea-ice loss boosts visual search: fish foraging and changing pelagic interactions in polar oceans.
Light is a central driver of biological processes and systems. Receding sea ice changes the lightscape of high-latitude oceans and more light will penetrate into the sea. This affects bottom-up control through primary productivity and top-down control through vision-based foraging. We model effects of sea-ice shading on visual search to develop a mechanistic understanding of how climate-driven ...
متن کاملCrossing oceans
Eve Marder explains why all scientists should spend time living and working in a foreign country.
متن کاملPolar Oceans
We survey progress in studies of ocean circulation, water mass formation, and ocean-ice interaction in both the Southern Ocean and the Arctic region during the period 1983-86. This review places emphasis on U.S. publications, but other significant work is included. It is not meant to be a complete synthesis of polar oceanography of the last four years, but rather to provide an overview of progr...
