More ocean acidification, less coral?

Co-authored by Erica Cirino Scientists have known for about 15 years that ocean acidification has made it more difficult for hard corals and shelled marine organisms to survive. To grow, hard corals as well as clams, oysters, and others pull calcium and carbonate molecules out of the water and join them together to create calcium…

Saving Coral Reefs Requires Halting Climate Change

Local conservation efforts are important to restoring and protecting coral reefs. However, if we don’t halt climate change those efforts will not be enough to save them. That’s why marine biologists and ocean lovers have their eyes on the COP 21 climate negotiations in Paris this week. Last year, I co-authored a New York Times…

Sixty Years of Data Show Waves are Getting Stronger, Threatening Coastlines and Infrastructure

By The Nature Conservancy’s Dr. Borja G. Reguero and Dr. Michael W. Beck Climate change is modifying the way our oceans work in many different ways, including ocean acidification and water warming. But where people really start to pay attention is where humans and oceans meet: the coast. On the coast, most people have heard…

Uniting Ocean and Earth for Climate Action

This winter, the United Nations Climate Change Conference (COP21) in Paris will feature one of the largest gatherings of world leaders to ever address global warming. The stage is set for all United Nations member states to come together and create an international agreement on the climate with the goal of keeping global warming below…

How Hosting an Edit-A-Thon Made Me Trust Wikipedia

The academic community has been wary of Wikipedia since it first came on the scene. Teachers have spent a decade warning their students not trust the online encyclopedia, concerned that because anyone can edit it, it might not be reliable. I’ll admit I first approached Wikipedia with caution, using it for quick reference but steering…

14 Ocean Conservation Wins of 2014

Chances are you’ve come across some ocean news lately. And it may even have been positive! Yes, the ocean is still in serious trouble due to overfishing, pollution, climate change, and habitat destruction, but there are more and more success stories to point to, and point I shall. #1. Big year for big marine reserves. Kiribati,…

Ocean Acidification from Domestic to International

  Since the industrial revolution began, we have released 2 trillion tons of carbon dioxide (CO2) into the atmosphere, and about one-third of it went into the ocean. We initially thought that the ocean taking up CO2 was a good thing – because it took it out of the atmosphere. Unfortunately, we were wrong.  There…

June 29, 2014: Refueling Satellites in Space, Sequencing the Koala Genome and More

Every week, embark with host Boyd Matson on an exploration of the latest discoveries and interviews with some of the most fascinating people on the planet, on National Geographic Weekend. This week, we walk in space to refuel a satellite, cure koalas of chlamydia, play soccer the Brazilian way, end elephant poaching in Tanzania, run out of air at the bottom of the Arctic Ocean, pair scientists with adventurers, road trip through the American South, and “revisit the Golden Age of Exploration.”

How Catfish Stalk Prey in the Dark

Catfish searching for prey in the dark detect slight chemical changes in the water produced by the breath of a sea worm, a new study says.

Will 2014 Be the Year of the Ocean?

The United Nations says 1998 was the Year of the Ocean, but I beg to differ. I’m fairly convinced that next year will be the year we see world leaders begin to take responsibility for the future of our ocean, and start to turn words into action. We’re also going to see an innovation explosion…

Newest XPRIZE Targets Ocean Health

Today, the latest XPRIZE competition was announced in Los Angeles, and this time the target is improving ocean health. Past XPRIZE efforts have focused on suborbital commercial spaceflight, efficient cars, and moon rovers. According to a spokesperson, the new prize was unveiled: On the heels of the successful Wendy Schmidt Oil Cleanup XCHALLENGE, the $2…

Arctic Experiencing More Than Just Melt

Carbon dioxide emissions are soaking into Arctic waters and affecting the chemistry of the ocean, a new report by the Arctic Monitoring and Assessment Program shows. Increasing carbon dioxide emissions and freshwater runoff challenge the ocean’s ability to neutralize acidification—an imbalance caused by absorption of the greenhouse gas from the air. The study said the Arctic’s cold water makes it more vulnerable to…

The Bottom Line: Embracing Ecosystem-Based Fisheries Management

Fishing for shad on the Potomac River at Fletcher’s Boathouse is a spring tradition for many Washington-area anglers, including me. As a food source for larger fish, birds of prey, and other animals, shad provide a great example of the interconnectedness of nature—which for decades hasn’t received enough attention from fisheries managers. Although we’ve made…

Making Climate a Blue Issue

Thundersnow, super-storms, dust storms, arctic melting, and coral bleaching have existed in the past but not as a regular part of our language till fossil-fuel fired climate change kicked in.  You know you’re in the greenhouse century when the 13 hottest years on record have all occurred since 1998 and last year, 2012, was the…

Unique Alaskan Orcas Slip Toward Extinction

One spill-echoing artwork, a ceramic wall-mounted sculpture called “Eyak’s Jaw,” was made in remembrance of the 20th anniversary of the Exxon Valdez oil spill. Within a rich bed of intertidal life forms – sea start, kelps, and urchins, a viewer glimpses the jawbone and conical teeth of an orca. The actual jawbone of the male…
