Geotimes

Geotimes is a free electronic newsfeed for the geoscience community. Originally launched as GeoSpectrum, a newsletter of the American Geosciences Institute in 1995, Geotimes has been reborn as the go-to source of information on AGI's 52 Member Societies. The American Geosciences Institute coordinates and edits Geotimes, but it is the result of contributed materials from societies, geoscience organizations and others in the community.

Do you have a geoscience blog or newsfeed with an RSS feed? It may be a good fit for Geotimes. To learn more about RSS or to submit information to Geotimes by email, please contact Joe Lilek at geotimes@americangeosciences.org.

Antarctic Fur Seal and columnar basalt

This female Fur Seal is sitting on hexagonal columns of basalt rock, that can be found in Pointe Suzanne at the extreme East of the Kerguelen Islands. Shot with a Canon 7D mark II ,24-105mm Canon lens, 105mm focal length, f/4, 1/800s, and ISO 400.

larvikite

larvikite (lar'-vik-ite). An alkalic syenite, grading to monzonite, composed of phenocrysts of two feldspars (esp. oligoclase and alkali feldspar), often intimately intergrown, which comprise up to 90% of the rock, with diopsidic augite and titanian augite as the chief mafic minerals, and accessory apatite (generally abundant), ilmenite, and titaniferous magnetite, and less commonly olivine, orthopyroxene, biotite, and quartz or feldspathoids (less than 10 percent by volume). Its name, given by Brögger in 1890, is derived from Larvik, Norway.

Crowned Elephant Seal

This female elephant seal is wearing a device recording unique oceanographic data in the remote Southern Ocean (temperature, salinity, fluorimetry and depth combined with a geolocalisation Argos system). The tag was attached before her post-breeding trip at sea, 4 months previously. It was 7 in the morning when I took this shot, she was just back on land and we were preparing our material to retrieve the tag. A Great Albatross is flying in the background. Shot with a Canon 7D mark II ,24-105mm Canon lens, 105mm focal length, f/4, 1/640s, and ISO 100.

Unwelcoming coastline

This jagged coastline belongs to the East island of the Crozet archipelago. The photo was taken from the "Marion Dufresne II" research vessel on its way bringing supplies to the French Southern and Antarctic Lands. Shot with a Canon 7D mark II ,24-105mm Canon lens, 105mm focal length, f/6.3, 1/400s, and ISO 100.

Windy conditions in Kerguelen islands

The Kerguelen islands are located in the latitude band of the Roaring Forties. The photo was shot from the beach of Cap Ratmanof at the very East of the main island. The westerly wind was 30 m/s, constraining us to stay in the wooden cabin and to stop our bio-logging research activities. The wildlife (King Penguins here) didn't seem very disturbed by this extreme weather. Shot with a Canon 7D mark II ,24-105mm Canon lens, 98mm focal length, f/4, 1/800s, and ISO 100.

hardness points

hardness points . Small, pointed pieces of minerals of different hardness, affixed to handles and used for testing the hardness of another mineral by ascertaining which point will scratch it. Minerals of hardness 6 to 10 on the Mohs scale are usually used as the points for testing gemstones. Because of the potential for damage, this test is not routinely used on faceted gemstones.

InTeGrate 2018 Spring Webinar Series Begins

Free and open to the public, the InTeGrate 2018 Spring Webinar Series will incorporate InTeGrate pedagogies into teaching practices, provide resources available for adoption, and create a forum for participants to learn and share teaching strategies. The series begins Monday, January 22 with the webinar Designing Activities for Effective Online Teaching.

An insight into life as a University Teaching Associate in numbers

In September 2017 I started my second short-term contract as a Teaching Associate at the University of Sheffield. I started my first teaching contract in July 2016, following a short and low-paid research contract after my PhD. The past year and a bit have been a steep learning curve, life as a PhD student really didn't do much to prepare for the teaching (and admin) side of academia. So at the start of this term I decided to track my working day to see what I spent my time on and how long I actually spent working!
