Although seagrasses and marine macroalgae (macro-autotrophs) play critical ecological roles in reef, lagoon, coastal and open-water ecosystems, their response to ocean acidification (OA) and climate change is not well understood. In this review, we examine marine macro-autotroph biochemistry and physiology relevant to their response to elevated dissolved inorganic carbon [DIC], ...

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

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 ...

Adverse Effects of Ocean Acidification on Early Development of Squid (Doryteuthis pealeii)

Anthropogenic carbon dioxide (CO2) is being absorbed into the ocean, altering seawater chemistry, with potentially negative impacts on a wide range of marine organisms. The early life stages of invertebrates with internal and external aragonite structures may be particularly vulnerable to this ocean acidification. Impacts to cephalopods, which form aragonite ...

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 ...
