Ocean Acidification in the Coastal Zone from and Organism's Perspective: Multipe System Parameters, Frequency Domains, and Habitats

Multiple natural and anthropogenic processes alter the carbonate chemistry of the coastal zone in ways that either exacerbate or mitigate ocean acidification effects. Freshwater inputs and multiple acid-base reactions change carbonate chemistry conditions, sometimes synergistically. The shallow nature of these systems results in strong benthic-pelagic coupling, and marine invertebrates at ...

Modeled Nitrogen Loading to Narragansett Bay: 1850 to 2015

Nutrient loading to estuaries with heavily populated watersheds can have profound ecological consequences. In evaluating policy options for managing nitrogen (N), it is helpful to understand current and historic spatial loading patterns to the system. We modeled N inputs to Narragansett Bay from 1850 to 2000, using data on population, ...

Episodic riverine influence on surface DIC in the coastal Gulf of Maine

  • By: petert

Anomalously high precipitation and river discharge during the spring of 2005 caused considerable freshening and depletion of dissolved inorganic carbon (DIC) in surface waters along the coastal Gulf of Maine. Surface pCO2 and total alkalinity (TA) were monitored by repeated underway sampling of a cross-shelf transect in the western Gulf of ...

The kinematic and hydrographic structure of the Gulf of Maine Coastal Current

  • By: petert

The Gulf of Maine Coastal Current (GMCC), which extends from southern Nova Scotia to Cape Cod Massachusetts, was investigated from 1998 to 2001 by means of extensive hydrographic surveys, current meter moorings, tracked drifters, and satellite-derived thermal imagery. The study focused on two principal branches of the GMCC, the Eastern ...

Changes in the timing of high river flows in New England over the 20th Century

  • Posted on: Wed, 03/30/2016 - 15:27
  • By: petert

The annual timing of river flows is a good indicator of climate-related changes, or lack of changes, for rivers with long-term data that drain unregulated basins with stable land use. Changes in the timing of annual winter/spring (January 1 to May 31) and fall (October 1 to December 31) center ...

Ocean and coastal acidification off New England and Nova Scotia

  • Posted on: Sun, 02/21/2016 - 15:47
  • By: petert

This Oceanography paper discusses ocean and coastal acidification processes specific to New England coastal and Nova Scotia shelf waters and reviews current understanding of the biological consequences most relevant to the region. It also identifies key research and monitoring needs to be addressed and highlight existing capacities that should be ...
