Influence of glacier melting and river discharges on the nutrient distribution and DIC recycling in the Southern Chilean Patagonia

International Atomic Energy Agency (IAEA) Publications

The Chilean Patagonia constitutes one of the most important and extensive fjord systems worldwide, therefore can be used as a natural laboratory to elucidate the pathway of both organic...

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...

Projected changes to growth and mortality of Hawaiian corals over the next 100 years

International Atomic Energy Agency (IAEA) Publications

Background Recent reviews suggest that the warming and acidification of ocean surface waters predicated by most accepted climate projections will lead to mass mortality and declining...

Publications

Seawater acidification induced immune function changes of haemocytes in Mytilus edulis: a comparative study of CO2 and HCl enrichment

International Atomic Energy Agency (IAEA) Publications

The present study was performed to evaluate the effects of CO2- or HCl-induced seawater acidification (pH 7.7 or 7.1; control: pH 8.1) on haemocytes of Mytilus edulis, and the changes in...

Synergistic effects of elevated carbon dioxide and sodium hypochlorite on survival and impairment of three phytoplankton species

International Atomic Energy Agency (IAEA) Publications

Sodium hypochlorite (NaOCl) is widely used to disinfect seawater in power plant cooling systems in order to reduce biofouling, and in ballast water treatment systems to prevent transport...

Publications

A year in the life of a central California kelp forest: physical and biological insights into biogeochemical variability

International Atomic Energy Agency (IAEA) Publications

Kelp forests are among the world's most productive marine ecosystems, yet little is known about their biogeochemistry. This study presents a 14-month time series (July 2013–August 2014)...
