Whales and the Pursuit of Oil: When Scientists and Big Oil Team Up

Whales and the pursuit of oil don’t tend to mix well. Companies often search using pulses, seismic surveys that employ sounds the same frequency as those that certain types of whales use to communicate.

Now, for the first time ever, an international group of scientists and an energy company have partnered to reduce the environmental impact of searching for oil and gas. It’s a move they hope will guide future interactions between the energy industry and the marine environment.

The International Union for Conservation of Nature (IUCN) created the Western Gray Whale Advisory Panel (WGWAP) in 2006 after Sakhalin Energy Investment Company wanted to conduct a survey for oil near Russia’s Sakhalin Island — in the same waters where a population of critically endangered gray whales feeds and breeds.

Many environmental groups, including the WWF, launched a campaign against the project because of worries about the impact on the whales, including ship strikes, sound disturbances and pollution, according to Carl Gustaf Lundin, IUCN Global Marine and Polar Program director.

“That really raised the profile of the project internationally,” Lundin told It forced Sakhalin to demonstrate a real commitment to mitigating any harm to the whale population, he added. (MORE: A New Way to Listen In On Dolphins and their Environment)

To help Sakhalin minimize its impact on the whales, scientists from the WGWAP began by studying the whales’ behaviors. They continued monitoring the whale population while the company worked, and adjusted the survey as needed, ultimately finding that the whales experienced few negative effects from the process. The researchers published their strategy in the journal Aquatic Mammals, in the hopes it could be a model for future surveys.

“What we’ve tried to do is provide the stepping stones [that] people need to follow,” Greg Donovan, chair of WGWAP, told “But it's a feedback process, so that you need to continually learn. You should never assume that what you're doing is working.”

It’s this feedback system that makes the new work “a real step-change” for seismic surveys, Nathan Merchant, a Syracuse University researcher who studies the effects of man-made sounds on marine life, told Merchant, who was not involved in this research, said this study is the first monitoring of noise levels in real time, allowing the team to intervene and stop the survey if necessary.

“It always feels a little strange talking about the environmental impact of seismic surveys on marine mammals when the whole issue is massively dwarfed by the question of whether we should be going to ever greater lengths to extract these fossil fuels in the first place,” Merchant said. “That said, if the impact these surveys have on the environment can be reduced, then by all means those measures should be taken.”

Whether to move away from fossil fuels is another question. Regardless, study lead author Doug Nowacek told that seismic surveys aren’t going away anytime soon. Companies survey existing oil fields every three to five years, and placing offshore wind turbines also requires surveying the sea floor.

“We’re not going to see a diminution of seismic surveys in the near future,” Nowacek said. “So hopefully what we’ve done will help inform those efforts.”

96L Slowly Organizing on its Way to the Lesser Antilles

By Dr. Jeff Masters
August 20, 2014

A tropical wave (96L) located near 11°N 53°W, several hundred miles east of the Lesser Antilles Islands, is headed west-northwestwards at about 10 - 15 mph. Satellite loops on Wednesday morning showed the wave had a broad, elongated surface circulation and a modest amount of heavy thunderstorm activity that was steadily increasing in areal coverage and intensity. The storm was poorly organized, though, with a clumpy appearance and just a few low-level spiral bands.

July 2014 Global Weather Extremes Summary

July was the 4th warmest such since 1880 according to NOAA and the 11th warmest according to NASA data (the difference in assessments is due to several factors which I’ll discuss in a future blog). It was unusually cool in the central portion of the U.S. while record warmth was observed in parts of the U.S. Northwest, Scandinavia and the Baltic nations. Several powerful typhoons made landfall in East Asia and Hurricane Arthur took a swipe at North Carolina.

What the 5th IPCC Assessment Doesn't Include

By Angela Fritz
September 27, 2013

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
