NOAA RESTORE Science Program Announces Next Federa...

This funding competition invites applications that propose to identify, track, understand, or predict trends and variability in the Gulf of Mexico’s living coastal and marine resources and the processes driving ...

Melting Antarctic Sea Ice Threatens Minke Whales (...

The Antarctic Peninsula is warming at rates much greater than the rest of the planet, leading to large losses of sea ice, prime habitat for minke whales. Tiny, shrimp-like crustaceans ...

Stakeholder Focus Groups Improve Communication of ...

Coastlines are composed of marshes, barrier islands, estuaries, and other environments that are ecologically, socially, and economically important. Coastal flooding is increasing in regularity and magnitude with increasing sea level ...

Living Shorelines in Chesapeake Bay Improve Benthi...

[a] Before-after control-impact [BACI] study locations in the upper (Windy Hill) and lower (Lynnhaven) Chesapeake Bay, USA. At Windy Hill: [b] aerial view of the living shoreline just after construction ...

Model Shows Ocean Acidification Could Outweigh Fis...

A new study, supported by NCCOS and the NOAA Ocean Acidification Program, examined a variety of marine ecosystems from the tropics to the arctic under different environmental conditions and management practices ...

Shoreline Hardening and Development Hurts Shorebir...

A new NCCOS-sponsored study shows that using artificial structures to protect coastal land and property from the sea can harm water birds. The research, conducted in Chesapeake Bay and published ...

Data & Publications

Physiological response and resilience of early life stage Eastern oysters (Crassostrea virginica) to past, present, and future ocean acidification

The Eastern oyster, Crassostrea virginica (Gmelin, 1791), is the second most valuable bivalve fishery in the USA and is sensitive to high levels of partial pressure of CO2 (pCO2). Here we present experiments that comprehensively examined how the ocean's past, ...

Potential climate-change impacts on the Chesapeake Bay

We review current understanding of the potential impact of climate change on the Chesapeake Bay. Scenarios for CO2 emissions indicate that by the end of the 21st century the Bay region will experience significant changes in climate forcings with respect ...

Potential larval sources, destinations, and self-seeding in the Mariana Archipelago documented using ocean drifters

Identifying transport pathways and sources of reef larvae is an essential component of ecosystem science. Ocean drifters tracked by satellite around the Mariana Archipelago were used to evaluate the possible pathways of transport among islands for passive larvae of reef ...

Prey size selection and bottom type influence multiple predator effects in a crab-bivalve system

Consumption by multiple conspecific or interspecific predators on shared prey is not always predicted when data from isolated predators are combined. Predator interactions can result in non-independent predator effects on prey, and may be influenced by prey size selection and ...

Processes controlling mid-water column oxygen minima over the Texas-Louisiana shelf

We investigate distributions of dissolved oxygen over the Texas-Louisiana shelf using spatially highly resolved observations in combination with a regional circulation model with simple oxygen dynamics. The observations were collected using a towed, undulating CTD during the Mechanisms Controlling Hypoxia ...

Projected impacts of future climate change, ocean acidification, and management on the US Atlantic sea scallop (Placopecten magellanicus) fishery

Ocean acidification has the potential to significantly impact both aquaculture and wild-caught mollusk fisheries around the world. In this work, we build upon a previously published integrated assessment model of the US Atlantic Sea Scallop (Placopecten magellanicus) fishery to determine ...

Quantifying the influence of cold water intrusions in a shallow, coastal system across contrasting years: Green Bay, Lake Michigan

We present water column thermal structure for two climatically different years: 2012, which experienced abnormally warm spring and summer air temperatures preceded by a relatively low ice winter and 2013, which experienced cooler than average spring and average summer air ...

Redox reactions and weak buffering capacity lead to acidification in the Chesapeake Bay

The combined effects of anthropogenic and biological CO2 inputs may lead to more rapid acidification in coastal waters compared to the open ocean. It is less clear, however, how redox reactions would contribute to acidification. Here we report estuarine acidification ...

Relative role of wind forcing and riverine nutrient input on the extent of hypoxia in the northern Gulf of Mexico

Seasonal hypoxia of the northern Gulf of Mexico has been observed for more than 25 years. It is generally accepted that the variation in the areal extent of hypoxia is determined by changes in nutrient addition from the Mississippi River ...

Responses of carbonate system CO2 flux to extended flooding in a semiarid subtropical estuary

Globally, estuaries are considered important CO2 sources to the atmosphere. However, estuarine water carbonate chemistry and CO2 flux studies have focused on temperate and high latitude regions, leaving a significant data gap in subtropical estuaries. In this study, we examined ...
