Gulf of Alaska 2004 Expedition. NOAA Office of Ocean Exploration
This week I have been researching images from deep-sea video on the home page for the NOAA Photo Library, which has housed ALL of the deep-sea and other imagery from NOAA's deep-sea expeditions since 2003, including those of the Okeanos Explorer!
Many of you know that I have participated in the last two
A powerful but deep earthquake occurred in the western portion of the Aleutian island arc at 11:53 AM local time on June 23. The earthquake was beneath the Bering Sea near Little Sitkin Island, Alaska at depth of 114 kilometers. A tsunami warning was
Pilot Drake Olson has identified another rock avalanche in Alaska, this time on the upper reaches of the Ferebee
An article on the Anchorage Daily News website explains why the oil and natural gas resources of Alaska are difficult to develop because the rules applied in other parts of the United States do not work well in Alaska’s unique
“Alaska is one of the best examples of how energy policy can change not just the trajectory of energy production, but how it can greatly improve the enhance the lives and livelihoods of its citizens.” Comment by Jack Gerard, President of the American Petroleum
“Alaska’s Pavlof Volcano is getting more active, say observers, with ash clouds rising to 22,000 feet and molten rock appearing on the surface.” Quoted from the Christian Science Monitor article. Related: Pavlof Volcano

Departure and return: Monday, June 23 at the Fairhaven dock, Bellingham, WA at 9:00 am, through Wednesday, June 25 between 3 and 5 pm at the same dock. · The boat “Zodiac” is berthed next to the Alaska
Ha, I predicted this earthquake for last Christmas, although I thought the earthquakes were marching to the north, and not south. So, not much of a prediction...
The 'Long March" is the natural series of earthquakes along this huge strike-slip fault. We had 2 M7+ earthquakes, and they were marching north. The next one I predicted would be in the armpit of Alaska. Three big M7.5's

Heliolites is an interesting coral that I thought was confined to the Silurian period, So I was surprised when my friend Nils sent me a specimen from the Devonian of Germany in a recent exchange. The specimen below comes from the Junkerberg Formation (Devonian, Eifelian stage) near Rommersheim, Germany.Previously I've blogged about specimens from the Silurian of Gotland, Sweden and Louisville, Kentucky. A search of the Fossilworks site (formerly Paleodb.org) shows that Heliolites is known up [...]
Today is the 50th anniversary of the Great Alaska Earthquake and The Washington Post has an article titled: “Remembering the 1964 Great Alaska Earthquake, the largest in U.S.
“In the next 50 years, as arctic systems warm, the release of carbon and nitrogen in permafrost could greatly exacerbate the warming phenomenon. Thawing is impacting ecosystems on land and offshore.” Quoted from the USGS
The Alaska Senate is debating a large project that would involve a natural gas liquefaction plant on the North Slope coastline, a natural gas pipeline system and a natural gas processing plant. The State might have a stake in the project. Presently, lots of natural gas on the North Slope is being flared because it
March 27 is the 50th anniversary of The Great Alaska Earthquake – America’s largest recorded earthquake. Geological information about the earthquake is presented in this eleven minute
Flying back from Alaska on yet another recent trip, I was able to spot Rose Spit, which featured as a Where in the West challenge back in October of 2010. The shape of the northeastern tip of Graham Island — an island in the Haida Gwaii, or Queen Charlotte Islands, off of the coast of British Columbia up near Prince Rupert — always fascinates me.
The northern portion of Graham Island, with
I am always interested in non-traditional data sets that can shed some light on climate changes. Ones that I’ve discussed previously are the frequency of closing of the Thames Barrier and the number of vineyards in England. With the exceptional warmth in Alaska last month (which of course was coupled with colder temperatures elsewhere), I
These charts show how proved oil reserves have been increasing in some parts of the United States – especially in North
“You might think it’d be hard not to notice 68 million tons of rock and debris suddenly crashing down a mountainside. But when one of the biggest landslides of the past four years occurred in a remote region of Alaska, researchers knew almost everything about it except its exact location.” Quoted from Adam Mann’s blog
The Landslide Blog has aerial photos and commentary on a rock avalanche that ran out about three miles over a glacier along the flank of Mount La Perouse in southeastern
Three out of the four times that I have flown between Anchorage and Nome, Alaska, the weather was overcast and clouds covered much of the landscape below. However, when I flew from Nome to Anchorage in August 2013 I was fortunate enough to fly on a day when skies were clear. I was thrilled to obtain a spectacular view of Denali, also known as Mt. McKinley, the highest peak in
The last deadly earthquake in Alaska occurred in 1964. It killed 131 people in Alaska and 16 more by tsunamis in Oregon and California. In the last 50 years there have been no earthquake deaths in Alaska even though several large earthquakes have occurred. Has that been
