In order to measure inputs, cycling, and loss of material in aquatic ecosystems, a wide range of compounds and analytical tools is now available. Biological markers are compounds, or groups of compoun...
A decade of Ridge 2000 and related research has yielded new and refined understanding of events and processes that occur on mid-ocean ridge and back-arc spreading centers, as reported in this special ...
This special issue of Oceanography is published in honor of the fiftieth anniversary of the Intergovernmental Oceanographic Commission (IOC). Established in 1960, IOC promotes international cooperatio...
Deep-sea benthic systems are notoriously difficult to sample. Even more than for other benthic systems, many flows among biological groups cannot be directly measured, and data sets remain incomplete...
Submarine hydrocarbon seeps are geologically driven “hotspots” of increased biological activity on the seabed. As part of the HERMES project, several sites of natural hydrocarbon seepage in the Euro...
During the European Commission’s Framework Six Programme, HERMES, we investigated three main areas along the European margin, each characterized by the presence of seep-related structures exhibiting...
Cold seeps, hydrothermal vents, deep water coral reefs, and submarine canyon systems are hotspot habitats characterized by intermediate to high fluid advection. They are shaped by a complex interpla...
The following is part 18 in a series on the National Science Foundation's Long-Term Ecological Research (LTER) Network.Visitparts one,two, three, four, five, six, seven,&...
A new study of the complex interplay between organisms and their environment shows that biodiversity—the variety of organisms living on Earth—is even more important to the healthy functioning of ecosy...
An extensive study of global habitat fragmentation--the division of habitats into smaller and more isolated patches--points to major trouble for the world's ecosystems.The study shows that 70 percent ...
Water is the most important factor controlling plant growth, primary production, and ecosystem stability in arid and semi-arid grasslands. Here we conducted a 2-year field study to explore the contrib...
Pannes are rare intradunal wetlands. Though small, they are known to exhibit extremely diverse and sensitive vegetation and are home to a number of reptile and amphibian species. In the United States,...
This study uses a variational data assimilation framework to simultaneously constrain a global ecosystem model with eddy covariance measurements of daily net ecosystem exchange (NEE) and latent heat (...
Carbon (C) and nitrogen (N) cycles are coupled in terrestrial ecosystems through multiple processes including photosynthesis, tissue allocation, respiration, N fixation, N uptake, and decompos...
The overall objective of the present study is to introduce the new ECOCLIMAP-II database for Europe, which is an upgrade for this region of the former initiative, ECOCLIMAP-I, already implemented at g...
