How Bringing Back The Great Whale Can Limit Climate Change (VIDEO)

The oceans are huge carbon sinks for the world. Fish and whales comprise only a tiny part of their overall biomass. Nevertheless, studies have shown that fishing and whaling by humans have altered the ocean’s carbon storage and sequestration capabilities by causing a change in the food chain, or a trophic cascade. As naturalist and

Sea Level Likely To Rise One Meter By 2100, Threatening Coastal Cities (Largest Ocean Science Survey Ever)

If greenhouse gas emissions remain at current levels, global sea-level rise will by 70 to 120 centimeters by 2100, according to the results of a new survey of 90 of the world’s most active ocean and climate scientists. The survey was conducted by researchers from the United States and Germany, and published in the recent Quaternary

Marine Species Used As Food Grown In Captivity For First Time

Eating sea anemones doesn’t sound that appealing, but the Snakelocks species (Anemonia sulcata) is regularly cooked and consumed in Spain near the Gulf of Cadiz. (Ortiguillas are marinated and deep-fried anemone.) Unfortunately, too many have been taken from the sea to be used as human food, so the Snakelocks species is in decline. Not only

New Report Card Shows Climate Change Affecting Australia's Oceans

Launched today by the CSIRO is the 2012 Marine Climate Change in Australia Report Card which demonstrates that climate change is having significant impacts on the marine ecosystems that border Australia. Aspects of the study include changes in sea temperature, sea level, the East Australian Current, the Leeuwin Current, and El Niño-Southern Oscillation, as well as marine

Planet Earth Still Absorbing Half of our Greenhouse Gases

Planet Earth’s oceans, forests, and other assorted ecosystems are continuing to soak up approximately half the carbon dioxide we humans pump into the atmosphere every day, even as those emissions continue to increase, once again belying the very little knowledge we currently have of our planet. “Globally, these carbon dioxide ‘sinks’ have roughly kept pace

Ocean Hotspots and Strengthening Winds Driving Ocean Currents Poleward

Oceanographers from across the world have identified a series of ocean hotspots that have been generated by strengthening wind systems across the planet that are successfully pushing oceanic current polewards, well beyond their known boundaries. The hotspots – locations where the temperature has increased outside of expected norms – have formed alongside ocean currents that

Ocean Acidity Alert

Ocean acidity is an issue we’ve written about numerous times, but really, it is such a critical issue, sometimes I feel like we should write about it everyday.

World's Marine Plankton in Peril – 40% Decline Since 1950

Phytoplankton–tiny, marine plants that formthe basis of our oceans’ food chain–absorb and sequester large amounts of CO2 from the atmosphere and generate half of the world’s oxygen supply. Given such an important ecosystem service as this, one would hope that our oceans’ algae numbers stay high…but, the results of a three year data analysis are anything but encouraging.

How We Wrecked the Ocean – Ecologist Jeremy Jackson Spells It Out [VIDEO]

In this talk, Jackson continuously returns to the three major factors that are dramatically altering our oceans: over-fishing, pollution, and climate change. These factors, he notes, do not arise and operate in isolation, but rather, they feedback into each other and “synergize” to make for a major, impending, ecological disaster.
