Rapid: Effect Of A Very Low Nao Event On The Abundance Of The Lipid-Rich Planktonic Copepod, Calanus Finmarchicus, In The Gulf Of Maine, Jeffrey Runge
Rapid: Effect Of A Very Low Nao Event On The Abundance Of The Lipid-Rich Planktonic Copepod, Calanus Finmarchicus, In The Gulf Of Maine, Jeffrey Runge
University of Maine Office of Research Administration: Grant Reports
Test the hypothesis that a distinctly lower abundance of the planktonic copepod, Calanus finmarchicus in the Gulf of Maine follows the occurrence of very negative winter phases of the North Atlantic Oscillation (NAO). In 2010, the station-based winter NAO index was -4.64, even more intense than the negative (-3.78) 1996 NAO winter index. If a two-year lagged relationship between very negative NAO winter indices and Calanus abundance in the Gulf of Maine is valid, cooler water from the Labrador Sea should replace Atlantic Temperate Slope Water in the GoM in 2012, inducing a major climatic ecosystem event on the New …

The main goal of our project is to understand the patterns of diversity and biogeography in marine copepods. To achieve this goal, we developed a unique modeling framework to simulate the trade-offs between growth, development, and fecundity in marine copepods.
We developed a new approach to modeling growth and development in metazoans. We applied this approach to marine copepods, and used it to understand relationships between copepod body size and temperature, copepod biodiversity patterns, and copepod biogeography. This project also provided support for experiments to look at how copepod body size impacts the particle size spectrum.
We used our model …
Collaborative Research: Interactive Effects Of Chronic N Deposition, Acidification, And Phosphorus Limitation On Coupled Element Cycling In Streams, Kevin S. Simon, Ivan J. Fernandez, Stephen Norton
Collaborative Research: Interactive Effects Of Chronic N Deposition, Acidification, And Phosphorus Limitation On Coupled Element Cycling In Streams, Kevin S. Simon, Ivan J. Fernandez, Stephen Norton
University of Maine Office of Research Administration: Grant Reports
Human activity has doubled the amount of nitrogen on the landscape, creating a pollution problem and changing the balance among multiple nutrients that limit biological activity in ecosystems. At the same time, other disturbances, such as acidification, interact with nitrogen enrichment in ways that strongly influence the productivity and health of terrestrial and aquatic ecosystems. This project examines the interactions among multiple elements and disturbances (nitrogen, phosphorus, metals, and acidification) along a continuum from the atmosphere through soils to streams. This project takes advantage of two unique experiments in which entire watersheds have been experimentally enriched with nitrogen and acid …

Objective I: Provide comprehensive volunteer monitoring of southern Maine beaches to improve state and municipal access to the quality-controlled beach elevation data, on a monthly and pre/post storm basis.
Objective II: Strengthen partnerships among beach profile monitoring stakeholders
Objective III: Expand teaching and learning opportunities for beach stakeholders by facilitating presentations by a range of new perspectives to constituents at the 2013 Maine Beaches Conference.
Objective IV: Publish and disseminate new and expanded data in the Maine Geological Survey’s biannual State o f Maine’s Beaches reports in 2013 and 2015.
