Ocean Acidification Decreases Growth and Development in American Lobster (Homarus americanus) Larvae

  • Posted on: Tue, 03/29/2016 - 17:03
  • By: petert

Ocean acidification resulting from the global increase in atmospheric CO2 concentration is emerging as a threat to marine species, including crustaceans. Fisheries involving the American lobster (Homarus americanus) are economically important in eastern Canada and United States. Based on ocean pH levels predicted for 2100, this study examined the effects ...

History of nutrient inputs to the northeastern United States, 1930-2000

Humans have dramatically altered nutrient cycles at local to global scales. We examined changes in anthropogenic nutrient inputs to the northeastern United States (NE) from 1930 to 2000. We created a comprehensive time series of anthropogenic N and P inputs to 437 counties in the NE at 5 year intervals. ...

Death by dissolution: Sediment saturation state as a mortality factor for juvenile bivalves

  • Posted on: Tue, 03/29/2016 - 16:36
  • By: petert

We show that death by dissolution is an important size-dependent mortality factor for juvenile bivalves. Utilizing a new experimental design, we were able to replicate saturation states in sediments after values frequently encountered by Mercenaria mercenaria in coastal deposits (Ωaragonite = 0.4 and 0.6). When 0.2-mm M. mercenariawere reared in sediments at Ωaragonite = 0.4 ...

Understanding Ocean Acidification Impacts on Organismal to Ecological Scales

This Oceanography article discusses the effectiveness and limitations of current research approaches used to understand how marine ecosystems and global elemental cycles will respond to changes in seawater carbonate chemistry in combination with other environmental perturbations such as warming, eutrophication, and deoxygenation. 

Effects of elevated CO2 in the early life stages of summer flounder, Paralichthys dentatus, and potential consequences of ocean acidification.

  • Posted on: Sat, 03/26/2016 - 14:27
  • By: petert

The limited available evidence about effects on marine fishes of high CO2 and associated acidification of oceans suggests that effects will differ across species, be subtle, and may interact with other stressors. This report is on the responses of an array of early life history features of summer flounder (Paralichthys ...

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 ...
