Long-Term Impacts of Anthropogenic Forcing on the Black Sea Ecosystem
Anthropogenic Forcing Black Sea Ecosystem
2015/7/27
The Black Sea, a nearly enclosed and isolated environment, has suffered from severe ecological changes during the last three decades. It has been converted from an oligotrophic (less than 100 grams of...
Anthropogenic Lead Emissions in the Ocean:The Evolving Global Experiment
Anthropogenic Lead Emissions Ocean Evolving Global Experiment

Time-Series View Changing Ocean Chemistry Due Ocean Uptake Anthropogenic CO2 Ocean Acidification
2015/7/17
Sustained observations provide critically needed data and understanding not only about ocean warming and water cycle reorganization (e.g., salinity changes), ocean eutrophication, and ocean deoxygenat...
A new method to diagnose the contribution of anthropogenic activities to temperature: temperature tagging
diagnose the contribution anthropogenic activities temperature temperature tagging
2014/12/16
This study presents a new methodology, called temperature tagging. It keeps track of the contributions of individual processes to temperature within a climate model simulation. As a first step and as ...
Effcts of Anthropogenic Stage Fluctuations on Surface Water/Ground Water Interactions Along the Deerfild River, Massachusett
Anthropogenic Stage Fluctuations Surface Water/Groundwater Interactions Deerfield River Massachusetts
2014/10/22
Understanding the connection of surface waters to ground-water systems is important when evaluating potential water resources. In the past surface waters and ground-water have been viewed as two diffe...
