Development of a Dynamic Biogeographic Information System for the Gulf of Maine
Dynamic Biogeographic Information System Gulf of Maine
2015/8/5
Central to the development of an inventory of marine life and improved conceptual understanding of the mechanisms that dynamically shape species distribution patterns needed for renewable resource man...
Population Dynamics, Chick Diet, and Foraging Behavior of the Razorbill (Alca torda) at Matinicus Rock, Maine
source-sink dynamics diving, temperature-depth recorder
2015/1/4
During the summers of 2007-2009, I studied the population growth and reproductive and foraging ecology of the Razorbill (Alca torda) at Matinicus Rock (MR), Maine. This medium-sized marine bird in the...
Response of a first-order stream in Maine to short-term in-stream acidification
stream acidification ion exchange
2009/3/24
An experimental short-term acidification with HCl at a first-order stream in central Maine, USA was used to study processes controlling the changes in stream chemistry and to assess the ability of str...
Winter Circulation in the Western Gulf of Maine：Part 1. Cooling and Water Mass Formation
Winter Circulation Western Gulf Water Mass Formation
2009/2/23
The mean circulation on the northeast continental shelf in the region of the Gulf of Mexico is discussed in terms of a simple box model, based on volume transports and mean salinities estimated from e...
Winter Circulation in the Western Gulf of Maine：Part 2. Current and Pressure Observations
Winter Circulation Pressure Observations Western Gulf
2009/2/13
The wintertime circulation in the western Gulf of Maine has been studied with a moored current, temperature and pressure array which was deployed from November 1974 to January 1975. These observations...
Modelling the Mean Barotropic Circulation in the Bay of Fundy and Gulf of Maine
nonlinear numerical models multi-grid model
2009/2/5
Two dimensional, nonlinear numerical models are used to study the residual barotropic circulation generated by tides and steady winds in the Bay of Fundy and Gulf of Maine. The first a multi-grid mode...
A Comparison of Georges Bank, Gulf of Maine and New England Shelf Tidal Dynamics
Georges Bank semidiurnal tidal currents Shelf Tidal Dynamics
2009/1/19
The semidiurnal tidal currents associated with the near-resonant response of the Gulf of Maine-Bay of Fundy system are amplified over the relatively shallow depths of Georges Bank, thus leading to enh...
The flow dynamics, volume, heat, and nitrogen transport, and water mass structure in the Northeast Channel (42°17′N, 65°58′W) are investigated using two years of moored velocity and temperature data. ...
The Steady-State Barotropic Response of the Gulf of Maine and Adjacent Regions to Surface Wind Stress
Steady-State Barotropic Gulf of Maine Surface Wind Stress
2009/1/12
The response of the Gulf of Maine region to steady, spatially uniform wind stress is examined using a linearized numerical model, with the influence of the strong tidal currents in the region included...
The M2 Tide and Its Residual on the Outer Banks of the Gulf of Maine
M2 Tide Outer Banks Gulf
2008/12/19
Tidal computations are reported for the Gulf of Maine with emphasis on its seaward banks. Georges Bank, Browns Bank, Nantucket Shoals, and the nearshore region off Cape Sable. The model is 3D and nonl...
Comparison of Two- and Three-Dimensional Model Simulation of the Effect of a Tidal Barrier on the Gulf of Maine Tides
Two- and Three-Dimensional Model Simulation Tidal Barrier Maine Tides
2008/12/18
Two-dimensional and three-dimensional tide models were used to simulate the M2 tide in the Gulf of Maine. Model estimates of changes to the tide caused by a tidal barrier in the upper Bay of Fundy wer...

A method to obtain an overall description of the Lagrangian circulation in complex two-dimensional time-periodic current fields is illustrated through its application to current fields from a numerica...
A Model Study of the Seasonal Circulation in the Gulf of Maine
Seasonal Circulation Gulf of Maine
2008/6/30
The Princeton Ocean Model is used to study the circulation in the Gulf of Maine and its seasonal transition in response to wind, surface heat flux, river discharge, and the M2 tide. The model has an o...
Methylmercury cycling in estuarine sediment pore waters (Penobscot River estuary, Maine, USA)
Methylmercury cycling estuarine sediment pore waters
2014/4/21
Particulate mercury (Hg) sequestered in coastal marine sediments may be efficiently methylated to highly toxic methylmercury (MeHg), thereby placing exposed organisms at risk of MeHg bioaccumulation. ...
