On the causes of mass extinctions

The temporal link between large igneous province (LIP) eruptions and at least half of the major extinctions of the Phanerozoic implies that large scale volcanism is the main driver of mass extinction. Here we review almost twenty biotic crises between the early Cambrian and end Cretaceous and explore potential causal mechanisms. Most extinctions are associated […]

How can you spot Amigo, the youngest member of our African penguin colony? He’s still sporting his juvenile coat, so look for the one penguin with a gray head in the crowd of dapper black-and-white birds!

Our commitment to ocean conservation is stronger than ever

A message from our executive director Julie Packard: For many of us, this past week has been a time of a time of deep reflection about what the future holds—for our families, for our country and for our planet.  All of us working for change, whether ocean conservation or human rights, will face daunting challenges and uncertainty in the time ahead.

From Marrakech, where the winds of change also blow

A funny thing happened at a meeting this week in Marrakech. Countries from around the world are meeting to decide how they will implement the landmark Paris Climate Agreement. In December last year, 195 countries agreed to aggressive targets to reduce emissions of greenhouse gases and limit global warming. As the COP22 meeting began, our […]

IAEA to inform COP22 participants on role of nuclear and isotopic techniques in climate action

The IAEA is participating in the Morocco Climate Change Conference, also known as COP22, over the next two weeks, and will inform delegates about the contribution of nuclear and isotopic techniques to combating climate change. Nuclear techniques can be used to both mitigate and help adapt to the consequences of climate change. The 22nd Conference […]

Event will put focus on ocean acidification in Maine

AUGUSTA, Maine — A group of environmentalists, academics and state leaders are hosting an event in the state’s capital city to discuss approaches to ocean pollution in Maine. The event will be held at the State House Legislative Council Room in Augusta on Tuesday and will focus on ocean acidification. The National Oceanic and Atmospheric […]

noaasanctuaries: It’s a mola mola! Usually seen floating solo, mola mola (also known as ocean sunfish) are the largest living bony fish in the sea. This one was spotted in Greater Farallones National Marine Sanctuary, but mola molas can be found all over the world.  These gigantic fish feed primarily on jellyfish. Show More Summary

Who needs an anemone limerick heading into the weekend? You do! Fish-eating anemones are most spectacular, and their venomous arms form a crown tentacular. So if you’re a little fish, stay away from that bright dish! Else, you’ll be quite late to your extracurricular… Photo by staffer Paul Ligorski.

A review of climate change and the implementation of marine biodiversity legislation in the United Kingdom

1. Marine legislation, the key means by which the conservation of marine biodiversity is achieved, has been developing since the 1960s. In recent decades, an increasing focus on ‘holistic’ policy development is evident, compared with earlier ‘piecemeal’ sectoral approaches. Show More Summary

Effects of elevated CO2 on predator avoidance behaviour by reef fishes is not altered by experimental test water

Pioneering studies into the effects of elevated CO2 on the behaviour of reef fishes often tested high-CO2 reared fish using control water in the test arena. While subsequent studies using rearing treatment water (control or high CO2) in the test arena have confirmed the effects of high CO2 on a range of reef fish behaviours, […]

The response of two species of unionid mussels to extended exposure to elevated carbon dioxide

Changes in environmental conditions can act as stressors, with potential consequences for the health and fitness of organisms. Rising levels of carbon dioxide (CO2) is one potential environmental stressor that is occurring more frequently in the environment and can be a stressor for aquatic organisms. In this study, the physiological responses of two species of […]

New HeroX Big Ocean Button Challenge seeks data apps to turn vast amounts of ocean data into useful products and services

Sponsored by XPRIZE and a follow-on to the Wendy Schmidt Ocean Health […]

Sea hare Aplysia punctata (Mollusca: Gastropoda) can maintain shell calcification under extreme ocean acidification

Ocean acidification is expected to cause energetic constraints upon marine calcifying organisms such as molluscs and echinoderms, because of the increased costs of building or maintaining shell material in lower pH. We examined metabolic...Show More Summary

Craig With Big Things (and Small Things)

I have a confession. I am obsessed with ridiculously large and small things. While other children impatiently anticipated toys for Christmas, I enjoyed just as much the miniature Christmas village my mother would place under the tree. I was particularly fascinated with the tiny frozen pond and ice skaters. I eagerly awaited the display being […]
