Gulp! Did you know moray eels have to constantly open and close their mouths to breathe?  During the day, moray eels sit in crevices with only their heads showing. At night they prowl across the reef looking for octopuses and small fishes. See them in the Splash Zone!

Latitudinal trends and drivers in the CO2–carbonic acid system of Papah?naumoku?kea Marine National Monument

Emissions of anthropogenic carbon dioxide (CO2) to the atmosphere and the consequent effects of climate change and ocean acidification on coral reef ecosystems have motivated significant interest in describing and understanding the CO2–carbonic acid system of diverse coral reef environments.

Ancient fish evolved gills to survive acidic oceans

Fish gills evolved to balance pH, not breathe, suggests a new study. This goes against the traditional assumption that gills first evolved so fish could get more oxygen as they became bigger and more active, say researchers in a recent issue of Scientific Reports. “When we think of the gill we automatically associate it with […]

Hagfish: Champions of CO2 tolerance question the origins of vertebrate gill function

The gill is widely accepted to have played a key role in the adaptive radiation of early vertebrates by supplanting the skin as the dominant site of gas exchange. However, in the most basal extant craniates, the hagfishes, gills play only a minor role in gas exchange. In contrast, we found hagfish gills to be […]

Study: world’s oceans facing irreversible damage without climate action

Unless ambitious action is taken to reduce carbon emissions the world’s oceans are facing dangerous and irreversible impact that could affect seafood supply, according to a new study. The report, which has been published in the journal Science, evaluated and compared two scenarios under two potential carbon dioxide emission pathways over this century. While both […]

Climate change could drain global seafood supplies

Seafood lovers are set to see less shellfish, salmon and other fish on their dinner plates as climate change warms the oceans and makes them more acidic. The findings from a series of studies out this week suggest rising greenhouse emissions from the burning of fossil fuels are adding stress to oceans that are already […]

Influence of CO2-induced seawater acidification on the development and lifetime reproduction of Tigriopus japonicus Mori, 1938

Ocean acidification is changing the carbonate system of the world’s oceans and has been driving all marine organisms to live in increasingly acidic environments. Tigriopus japonicus is an ideal standard test animal in sea water. In the...Show More Summary

7-6-15 Free the Snake River Video

If you haven't seen this then it's a must watch. If you have, then watch it again! The Lower Snake dams "are largely responsible for the destruction of the salmon runs that we used to see all the way up into the Rocky Mountains in Idaho." – Bruce Babbitt, former U.S. Show More Summary

The Earth’s oceans are DYING: Researchers warn time is running out for marine life due to global warming

Time is rapidly running out for the world’s oceans and the creatures that live in them as the Earth’s climate continues to warm, say scientists. Only ‘immediate and substantial’ reductions in greenhouse gas emissions can hope to prevent ‘massive’ impacts on marine ecosystems, warn the experts. Researchers compared the fate of the oceans under two […]

New study warns of dangerous climate change risks to the Earth’s oceans

A new paper just published in Science summarizes the projected impacts of climate change on the world’s oceans, and consequently on humans and our economy. The study concludes that global warming beyond the international limit of 2°C above pre-industrial temperatures would pose serious threats to marine ecosystems and their millions of human dependents. It builds […]

CO2 emissions threaten ocean crisis

Scientists have warned that marine life will be irreversibly changed unless CO2 emissions are drastically cut. Writing in Science, experts say the oceans are heating, losing oxygen and becoming more acidic because of CO2. They warn that the 2C maximum temperature rise for climate change agreed by governments will not prevent dramatic impacts on ocean […]

Proxy development and application for reconstructing the surface ocean carbonate system

Over the last two centuries, human activities have led to an unprecedented rate of carbon input into the atmosphere and oceans resulting in an alarmingly rapid decline in surface ocean pH, a process referred to as ocean acidification (OA). This process is leading to an observed decline in the carbonate ion concentrations ([CO32-]) in seawater […]

Synergistic effects of hypoxia and increasing CO2 on benthic invertebrates of the central Chilean coast

Ocean acidification and hypoxic events are an increasing worldwide problem, but the synergetic effects of these factors are seldom explored. However, this synergetic occurrence of stressors is prevalent. The coastline of Chile not only suffers from coastal hypoxia but the cold, oxygen-poor waters in upwelling events are also supersaturated in CO2, a study site to […]

Impact of atmospheric pCO2, seawater temperature, and calcification rate on the ?18O and ?13C composition of echinoid calcite (Echinometra viridis)

The tropical echinoid Echinometra viridis was reared in controlled laboratory experiments at temperatures of approximately 20°C and 30°C to mimic winter and summer temperatures and at carbon dioxide (CO2) partial pressures of approximately 487 ppm-v and 805 ppm-v to simulate current and predicted-end-of-century levels.

What are the major global threats and impacts in marine environments? Investigating the contours of a shared perception among marine scientists from the bottom-up

Marine scientists broadly agree on which major processes influence the sustainability of marine environments worldwide. Recent studies argue that such shared perceptions crucially shape scientific agendas and are subject to a confirmation bias. Show More Summary

Pteropod time series from the North Western Mediterranean (1967-2003): impacts of pH and climate variability

Environmental changes resulting from anthropogenic CO2 emissions occur at global and local levels and have potentially harmful effects, particularly for calcifying taxa in the marine environment. A time series of pteropod abundance covering the period 1967-2003 was isolated from the Point B (northwestern Ligurian Sea) zooplankton time series. Show More Summary
