NECAN Monitoring Priorities in the Northeast Workshop Report

  • Posted on: Fri, 02/16/2024 - 13:08
  • By: jackie

The Northeast Coastal Acidification Network (NECAN) held a workshop November 2-3, 2023 to identify and recommend monitoring priorities for ocean acidification in the NECAN region. Prior to the workshop, NECAN had submitted monitoring needs to the Interagency Working Group on Ocean Acidification. One of the outcomes of the workshop was ...

The impact of oyster aquaculture on the estuarine carbonate system

Abstract: Many studies have examined the vulnerability of calcifying organisms, such as the eastern oyster (Crassostrea virginica), to externally forced ocean acidification, but the opposite interaction whereby oysters alter their local carbonate conditions has received far less attention. We present an exploratory model for isolating the impact that net calcification and ...

Controls on buffering and coastal acidification in a temperate estuary

  • Posted on: Thu, 07/14/2022 - 13:18
  • By: kcanesi

Abstract: Estuaries may be uniquely susceptible to the combined acidification pressures of atmospherically driven ocean acidification (OA), biologically driven CO2 inputs from the estuary itself, and terrestrially derived freshwater inputs. This study utilized continuous measurements of total alkalinity (TA) and the partial pressure of carbon dioxide (pCO2) from the mouth of ...

EPA Guidelines for Measuring Changes in Seawater pH and Associated Carbonate Chemistry in Coastal Environments of the Eastern United States

These guidelines are written for a variety of audiences ranging from shellfish growers interested in monitoring pH with inexpensive equipment to citizen monitoring groups to advanced chemistry laboratories interested in expanding existing capabilities. The purpose is to give an overview of available sampling, analytical and data reporting approaches that will ...

Coral reefs will transition to net dissolving before end of century

  • By: kcanesi

Ocean acidification refers to the lowering of the ocean’s pH due to the uptake of anthropogenic CO2 from the atmosphere. Coral reef calcification is expected to decrease as the oceans become more acidic. Dissolving calcium carbonate (CaCO3) sands could greatly exacerbate reef loss associated with reduced calcification but is presently poorly ...

Continental shelves as a variable but increasing global sink for atmospheric carbon dioxide

  • Posted on: Thu, 02/01/2018 - 12:24
  • By: kcanesi

It has been speculated that the partial pressure of carbon dioxide (pCO2) in shelf waters may lag the rise in atmospheric CO2. Here, we show that this is the case across many shelf regions, implying a tendency for enhanced shelf uptake of atmospheric CO2. This result is based on analysis ...
