The color of the year is Living Coral [World Oceans Day/National Ocean Month]

Sun, 06/16/2019 - 9:28pm

Pantone describes its 2019 color of the year as "an animating and life-affirming coral hue with a golden undertone that energizes and enlivens with a softer edge." Others feel it is "a stinging reminder of the cycle of constant growth driven by fossil fuels that’s brought the world to this point."

Sols 2437-2439: An oasis of rock in a sea of pebbles

Sat, 06/15/2019 - 8:00pm

We are investigating the ridges which are such a prominent feature in this section of Glen Torridon. The ridges appear to be composed of sand and pebbles, capped with layered bedrock.

Sol 2436: So many choices, so little time

Sat, 06/15/2019 - 9:00am

"...We eventually decided to drive to a small outcrop patch about 30 m away, where we will be able to invest time studying the outcrop while also gazing up along the ridge to look for other bedrock exposures and clues about its structure."

Varied Snowcover Extent Diagnostic of Glacier NP Glacier Climate Response

Fri, 06/14/2019 - 4:53pm

Snowcover extent in Landsat images from August, 1998 and 2018. S=Sperry, H=Harrison, J=Jackson, B=Blackfoot and P=Pumpelly Five of the eight largest glaciers in Glacier National Park are clustered in a small area: Jackson Glacier, Sperry Glacier, Pumpelly Glacier, Harrison Glacier, and Blackfoot Glacier. The USGS in Glacier National Park has over the last 15 years maintained an extensive glacier monitoring program led by Dan Fagre.  This program has led to consistent …

Building AGU: Achieving Sustainability and Leading by Example

Fri, 06/14/2019 - 12:38pm

This post was originally published on the Getting to Zero Forum blog.  As AGU, a global community of 60,000 Earth and space scientists, celebrates its Centennial year, we don’t just reflect on past accomplishments. Instead, we’re also looking to the future to transform and improve our world. This spirit is what drove AGU’s decision to renovate its headquarters building in Washington, D.C. When AGU’s original building and infrastructure began to …

Friday fold: kinked cleavage at Harpers Ferry

Fri, 06/14/2019 - 12:27pm

Last weekend was the annual meeting of the eastern section of the National Association of Geoscience Teachers. On Friday afternoon, we visited Harpers Ferry, West Virginia, and my colleague Beth Doyle led a great field trip to examine the rocks exposed there. This was my favorite outcrop we saw: Here is a close up of this outcrop, which is framed by (anthropogenic) rock wall: Dipping shallowly from upper left to …

Monitoring a mystery bird in Yakutat

Fri, 06/14/2019 - 9:35am

Arctic terns and Aleutian terns gather together on ocean spits to scratch out nest cups. Each is a graceful creature that distinguishes itself from a gull by the incessant slicing of its sharp wings through the air.

Seeking the Seeps

Thu, 06/13/2019 - 2:49pm

The unusually bright Oregon sun beams down on me as I watch the soaring Astoria bridge recede into the background. The R/V Falkor has just pushed back from the dock and we’re steaming into the great Columbia River. Looking ahead, I can see twin points of land, framing the mouth of the Columbia like a giant crab claw.

Seeking Space Rocks: The search continues

Wed, 06/12/2019 - 8:38pm

The seaborne portion of our expedition has ended, but the land-based search begins. In the laboratory, all the samples are examined with fresh eyes, using instruments that enable Dr. Marc Fries to “see” potential meteorites at a much finer scale.

A dedicated, university-based team that bridges the science-policy divide

Wed, 06/12/2019 - 11:23am

Dr. Michelle McCrackin is a biogeochemist interested in how agriculture, urbanization, energy production, and land use change have influenced nutrient cycling in watersheds, with particular interest in lake and coastal ecosystems. She is a researcher with Baltic Eye in Stockholm, Sweden.   For the past five years, I have been part of a novel team, called Baltic Eye, at Stockholm University’s Baltic Sea Centre. Our team is composed of researchers, …

Translating the wonder of the sea

Tue, 06/11/2019 - 1:11pm

I am quite sure the very first explorers were crazy. Looking out to the horizon and seeing nothing but water, why on earth would anyone ever traverse those endless waves, into the unknown? Of course, it is the same reason that compels us to tackle new problems and learn new things every day: an interest in the world around us; curiosity.

According to plan

Mon, 06/10/2019 - 7:26pm

After picking up the science team in Astoria, we headed back out to sea! This time we headed northward to the Olympic Coast National Marine Sanctuary off the coast of Washington State. The aim of this leg is to try to locate and recover fragments of a meteor strike recorded off the coast.

Asejiaguo Glacier in Landsat images from 1993 and 2018.  The yellow arrow indicates the 2018 terminus and the red arrow the 1993 terminus location.  Point 1 and 2 are areas of expanding bedrock in the 5400-5600 m. Asejiaguo Glacier drains east from the China-Nepal Border and is at the headwaters of the Yarlung Tsangpo, which becomes the Brahmaputra River.  The Yarlung Tsangpo powers the 510 MW Zangmu Hydropower Station.  Gardelle …

Presidential proclamations of National Ocean Month, 2006-2019

Mon, 06/10/2019 - 8:21am

Did you know that NOAA wasn't even mentioned in the first Presidential proclamation for this celebration? And the first celebration was for a National Ocean Week, not a month? And that the Great Lakes are mentioned in several of these statements? Explore links to these Presidential proclamations going back to President Bush in 2006.
