Perception and response of the U.S. West Coast shellfish industry to ocean acidification: the voice of the canaries in the coal mine
International Atomic Energy Agency (IAEA) Publications
In the mid-2000s the U.S. west coast oyster industry experienced several years of significant production failures. This industry has been referred to as the “canary in a coal mine” for...

The influence of Pacific Equatorial Water on fish diversity in the southern California Current System
International Atomic Energy Agency (IAEA) Publications
The California Undercurrent transports Pacific Equatorial Water (PEW) into the Southern California Bight from the eastern tropical Pacific Ocean. PEW is characterized by higher...

IAEA Marine Information System (MARiS)
International Atomic Energy Agency (IAEA) Publications
The IAEA's Marine Information System (MARiS) allows the search and recovery of more than 528,000 measurements of radioactivity data in the marine environment found in seawater, biota,...

Using expert judgment to estimate marine ecosystem vulnerability in the California Current
International Atomic Energy Agency (IAEA) Publications
As resource management and conservation efforts move toward multi-sector, ecosystem-based approaches, we need methods for comparing the varying responses of ecosystems to the impacts of...

Habitat compression and expansion of sea urchins in response to changing climate conditions on the California continental shelf and slope (1994–2013)
International Atomic Energy Agency (IAEA) Publications
Echinoid sea urchins with distributions along the continental shelf and slope of the eastern Pacific often dominate the megafauna community. This occurs despite their exposure to...

Anthropogenic carbon distribution in the eastern South Pacific Ocean
International Atomic Energy Agency (IAEA) Publications
We present results of the CO2/carbonate system from the BIOSOPE cruise in the Eastern South Pacific Ocean, in an area not sampled previously. In particular, we present estimates of the...

Phytoplankton do not produce carbon-rich organic matter in high CO2 oceans
International Atomic Energy Agency (IAEA) Publications
The ocean is a substantial sink for atmospheric carbon dioxide (CO2) released as a result of human activities. Over the coming decades the dissolved inorganic C concentration in the...

Risks of hypoxia and acidification in the high energy coastal environment near Victoria, Canada's untreated municipal sewage outfalls
International Atomic Energy Agency (IAEA) Publications
Wastewater disposal often has deleterious impacts on the receiving environment. Low dissolved oxygen levels are particularly concerning. Here, we investigate the impacts on dissolved...

Permeable coral reef sediment dissolution driven by elevated CO2 and porewater advection
International Atomic Energy Agency (IAEA) Publications
Ocean acidification (OA) is expected to drive the transition of coral reef ecosystems from net calcium carbonate (CaCO3) precipitating to net dissolving within the next century. Although...

Detrimental effects of reduced seawater pH on the early development of the Pacific abalone
International Atomic Energy Agency (IAEA) Publications
The hatching process of the Pacific abalone Haliotis discus hannai was prolonged at a pH of 7.6 and pH 7.3, and the embryonic developmental success was reduced. The hatching rate at pH...

Dissolution: the Achilles' heel of the triton shell in an acidifying ocean
International Atomic Energy Agency (IAEA) Publications
Ocean acidification is expected to negatively impact many calcifying marine organisms by impairing their ability to build their protective shells and skeletons, and by causing dissolution...

Ocean acidification in the California Current System
International Atomic Energy Agency (IAEA) Publications
Eastern boundary upwelling systems (EBUS) are naturally more acidic than most of the rest of the surface ocean. Observations of EBUS already show pH values and saturation states with...

Uranium in larval shells as a barometer of molluscan ocean acidification exposure
International Atomic Energy Agency (IAEA) Publications
As the ocean undergoes acidification, marine organisms will become increasingly exposed to reduced pH, yet variability in many coastal settings complicates our ability to accurately...

Effects of fishing and acidification-related benthic mortality on the southeast Australian marine ecosystem
International Atomic Energy Agency (IAEA) Publications
Oceanic uptake of anthropogenic carbon dioxide (CO2) is altering the carbonate chemistry of seawater, with potentially negative consequences for many calcifying marine organisms. At the...

Changes in water quality following opening and closure of a bar-built estuary (Pescadero, California)
International Atomic Energy Agency (IAEA) Publications
Bar-built estuaries are coastal environments characterized by the partial closure of the estuary's mouth with a sandbar barrier for extended periods (closed state). Through natural events...

Deducing acidification rates based on short-term time series
International Atomic Energy Agency (IAEA) Publications
We show that, statistically, the simple linear regression (SLR)-determined rate of temporal change in seawater pH ($β$pH), the so-called acidification rate, can be expressed as a linear...

Growing up in the temperate zone: age, growth, calcification and carbonate mineralogy of Melicerita chathamensis (Bryozoa) in southern New Zealand
International Atomic Energy Agency (IAEA) Publications
The cheilostome bryozoan Melicerita chathamensis from the continental shelf around southern New Zealand is unusual in having macroscopic annual growth checks. It thus presents an...

The influence of abrupt increases in seawater pCO2 on plankton productivity in the subtropical North Pacific Ocean
International Atomic Energy Agency (IAEA) Publications
We conducted a series of experiments to examine short-term (2-5 days) effects of abrupt increases in the partial pressure of carbon dioxide (pCO2) in seawater on rates of primary and...

Nutrient pollution disrupts key ecosystem functions on coral reefs
International Atomic Energy Agency (IAEA) Publications
There is a long history of examining the impacts of nutrient pollution and pH on coral reefs. However, little is known about how these two stressors interact and influence coral reef...

Not all sponges will thrive in a high-CO2 ocean: review of the mineralogy of calcifying sponges
International Atomic Energy Agency (IAEA) Publications
Most marine sponges precipitate silicate skeletal elements, and it has been predicted that they would be among the few “winners” among invertebrates in an acidifying, high-CO2 ocean. But...
