By Kim DeRose, kderose@support.ucla.edu 16 June 2011 Fluctuations in climate can drastically affect the habitability of marine ecosystems, according to a new study by UCLA scientists that examined the expansion and contraction of low-oxygen zones in the ocean. The UCLA research team, led by assistant professor of atmospheric and oceanic sciences Curtis Deutsch, used a specialized […]
By Doyle Rice, USA TODAY16 Jun 2011 The so-called dead zone in the Gulf of Mexico — a region of oxygen-depleted water off the Louisiana and Texas coasts that is harmful to sea life — is predicted to be the largest ever recorded when it develops later this summer, scientists report. The unusually large size […]
By JUSTIN GILLIS4 June 2011 On a warming planet, humanity faces a great challenge in feeding itself at reasonable cost in the coming century, as I explain in Sunday’s paper. An issue I raise only in passing in the article is that agriculture itself is one of the earth’s greatest environmental threats. To put a […]
ScienceDaily (May 26, 2011) — A technical comment published in the May 27 edition of the journal Science casts doubt on a widely publicized study that concluded that a bacterial bloom in the Gulf of Mexico consumed the methane discharged from the Deepwater Horizon well. The debate has implications for the Gulf of Mexico ecosystem […]

But now, sewage-derived nitrogen is increasingly becoming the top source of such pollution […]
By Ben Raines, Press-Register 21 April 2011 Researchers contacted by the Press-Register expressed almost uniform surprise at the apparent rebound in nearshore environments a year after 200 million gallons of oil began pouring into the Gulf of Mexico. With the caveat that much remains unknown — and problems could still emerge at any time — […]
After the biggest mass extinction in Earth’s history – 250 million years ago – algae and bacteria in the ocean rebounded so fast that they consumed virtually all the oxygen in the sea, slowing the recovery of the rest of marine animals for several million years. BY LOUIS BERGERONMarch 24, 2011 A mass extinction is […]
By Andrew BlanksteinMarch 8, 2011 Authorities in Redondo Beach are investigating what killed millions of fish over the last day at King Harbor Marina. Fish, including anchovies, sardines and mackerel were floating lifeless in Basins 1 and 2 of the north side of King Harbor Marina. “There’s basically fish everywhere you go in the harbor,” […]
