Subarctic Cetaceans in the Southern Chukchi Sea: Evidence of Recovery or Response to a Changing Ecosystem
Production sea ice the bering strait tourism sea ice cover
2015/7/16
The southern Chukchi Sea is one of the most productive areas in the world ocean. Over the past decade, there have been dramatic changes in this region in sea ice cover and in Bering Strait inflow, and...
Legacy of the US GLOBEC Program: Current and Potential Contributions to Marine Ecosystem-Based Management
Marine biological resource management ecosystem climate environment dynamics
2015/7/16
Management of living marine resources is undergoing a profound transition toward a more holistic, ecosystem-based paradigm. The interplay of climate and environmental forcing, ecosystem structure and ...
Uncertainty Management in Coupled Physical-Biological Lower Trophic Level Ocean Ecosystem Models
Lower trophic level Marine ecosystem model Marine geochemistry the earth's climate system
2015/7/16
Lower trophic level (LTL) ocean ecosystem models are important tools for understanding ocean biogeochemical variability and its role in Earth's climate system. These models are often replete with para...
Synthesis of Pacific Ocean Climate and Ecosystem Dynamics

2015/7/16
The goal of the Pacific Ocean Boundary Ecosystem and Climate Study (POBEX) was to diagnose the large-scale climate controls on regional transport dynamics and lower trophic marine ecosystem variabilit...
Advances in Marine Ecosystem Dynamics from US GLOBEC: The Horizontal-Advection Bottom-up Forcing Paradigm
Global ocean ecosystem dynamics ecosystem climate Marine ecosystems
2015/7/16
A primary focus of the US Global Ocean Ecosystem Dynamics (GLOBEC) program was to identify the mechanisms of ecosystem response to large-scale climate forcing under the assumption that bottom-up forci...

Widespread variability in overnight patterns of ecosystem respiration linked to gradients in dissolved organic matter, residence time, and productivity in a global set of lakes。
Temporal dynamics of seston: A recurring nighttime peak and seasonal shifts in composition in a stream ecosystem
A recurring nighttime peak seasonal shifts
2014/4/17
We measured the baseflow concentration and composition of seston and suspended particulate organic carbon
(POC) over a 1-yr period in White Clay Creek, a third-order stream in the southeastern Pennsy...
Flooding and arsenic contamination: Influences on ecosystem structure and function in an Appalachian headwater stream
Flooding arsenic contamination ecosystem structure
2014/4/22
We investigated the influence of flooding and chronic arsenic contamination on ecosystem structure and
function in a headwater stream adjacent to an abandoned arsenic (As) mine using an upstream (ref...
Copepod biodiversity as an indicator of changes in ocean and climate conditions of the northern California current ecosystem
Copepod biodiversity ocean and climate conditions
2014/5/5
We evaluated copepod taxonomic diversity as a potential biological indicator of ocean conditions in the
northeast Pacific Ocean using data collected biweekly between May 1996 and December 2004 and fr...
A new numerical technique for tracking chemical species in a multisource, coastal ecosystem applied to nitrogen causing Ulva blooms in the Bay of Brest (France)
tracking chemical species multisource
2014/4/30
A new numerical technique is presented that allows the tracking of any chemical element from any source in a
simulated foodweb, for instance assessing the proportion of these sources (river loadings,...

Floods can cause large interannual differences in littoral net ecosystem productivity
interannual differences littoral net ecosystem productivity
2014/5/19
Littoral wetlands comprise a terrestrial to aquatic continuum along which carbon dioxide is exchanged with the
atmosphere and organic carbon is transferred to lakes. Net ecosystem productivity—the di...
