Making Connections

5 hours 46 min ago
As participants ask questions about whether the multibeam affects marine mammals and what kind of schooling is needed to be just like Colleen, it is clear that the public is curious about and excited to be a part of what happens on board. I know we have touched young hearts and minds back on land. As each of us go back to our respective communities, we will continue to share our experiences from Falkor and promote the understanding and mindfulness the ship stands for.

Monday Geology Picture: Intaka Island Salt Pan

5 hours 47 min ago
For this week’s picture, here’s a view of a salt pan on Intaka Island, a small nature reserve in the Century City area of Cape Town. I often go to Intaka Island to paddle in a kayak on the canals surrounding the island. On Saturday morning I went for one of my usual paddles, and then in the afternoon I joined some friends for a nature walk on the island itself. …

Back for More Beaming

7 hours 10 min ago
Aloha readers! I’m baaack, for another oceanographic expedition on mighty R/V Falkor. I say mighty, because her previous life was as a North Sea fisheries enforcement vessel and so she was initially designed for speed and sturdiness to survive the harsh conditions. At the beginning of our journey we were bashing through the trade seas and currents north of the equator on the way to our study site near Johnston Atoll. It was a bit of a rough ride, although we felt safe and secure in the belly of mighty Falkor, and the conditions steadily improved.

Shear zones in Scottish gabbros

A quest to visit the "first shear zones" described in the scientific literature leads to an alternate location, and some GIGAmacro images of samples from the real, original spot.

The need for action through scicomm

11 hours 16 min ago
By Shane M Hanlon “What do you do?” This is a question that I’m asked almost daily as a DC resident where interest in one’s profession is only surpassed by interest in politics. But back in 2010, when I was a 2nd-year PhD student, I was not used to this question. I had successfully avoided (i.e. didn’t try) making friends outside of my program during my first year, so when I …

Future shock – the failure to learn from the 2015 earthquake in Nepal

To mark National Earthquake Day, the Nepal Times has a series of articles entitled Future Shock that examines the failure to learn from the 2015 earthquake

The Most Beloved Weather Forecast You’ve Never Heard About

17 hours 21 min ago
If you are reading this from the UK, you know already what I’m writing about, but to those elsewhere, the “Shipping Forecast” is mostly unknown. It’s heard on BBC Radio 4 each day, and It’s far more than a weather forecast, it’s an institution, with many more listeners on dry land than at sea! What is it about this 12 minutes of radio that so many (I included) love? Its constancy …

Sols 1579-1582: A 4-sol plan

Sun, 01/15/2017 - 11:00pm
We'll use the laser to zap rock targets "Oak Bay" and "Rockport" and take Right Mastcam images of them.

Sol 1578: Investigating sedimentary structures

Sun, 01/15/2017 - 2:00am
Today’s plan provided another opportunity for touch and go contact science, starting with MAHLI imaging of the “Megunticook” outcrop.

Scientists try to mitigate methane, from cows

Fri, 01/13/2017 - 3:00pm
There are about 33 million cattle in Mexico, where a few scientists are experimenting to concoct a cow diet that will reduce methane emissions.

Get to know YESS: The Young Earth System Scientists community

Fri, 01/13/2017 - 2:17pm
Earlier this week, On the Job featured a recap of the APECS Cryosphere Careers panel that took place  at the 2016 AGU Fall Meeting. Today, we feature another group that presented at Fall Meeting.  Representatives from the Young Earth System Scientists (YESS) community gave a presentation in the AGU Career Resource Theater to share with early career AGU attendees background on YESS and how they can get involved. More information is …

Changing atmospheric conditions may contribute to stronger ocean wave activity on the Antarctic Peninsula

Fri, 01/13/2017 - 11:23am
A new study provides important details on the extent of sea ice, which can protect ice shelves from the impacts of ocean storms, in the Antarctic Peninsula.

Friday fold: Smaull Graywacke at Saligo Bay, Islay

Fri, 01/13/2017 - 8:13am
On the western coast of Islay, Saligo Bay showcases turbidites of the Neoproterozoic Colonsay Group. The Smaull Graywacke shows Caledonian (late Ordovician) folding and cleavage superimposed on world-class graded bedding. There's also a nice dolerite dike to examine.

A Top Scientist Who Makes The Complex Simple

Fri, 01/13/2017 - 2:53am
I could not make it this year, but the Glen Gerberg Weather Summit (that my friend Dave Jones at StormCenter Communications hosts each January) is one of the best science seminars I’ve ever attended. One of the speakers on Wednesday was Dr. Jim White, who I spent two weeks with (as his guest) on top of the Greenland Ice cap at NEEM. Jim is a GREAT science communicator, with an …

Recent Climate Change Impacts on Mountain Glaciers – Volume

Thu, 01/12/2017 - 4:47pm
Landsat Image of glaciers examined in the Himalaya Range: Chapter 10 that straddles a portion of Sikkim, Nepal and Tibet, China. Notice the number that end in expanding proglacial lakes.  This January a book I authored has been published by Wiley. The goal of this volume is to tell the story, glacier by glacier, of response to climate change from 1984-2015. Of the 165 glaciers examined in 10 different alpine …

After the drive and the post-drive imaging needed to plan Sol 1578 activities, Navcam will acquire a panorama and search for dust devils and clouds.

The Deep End

Wed, 01/11/2017 - 12:03pm
The challenge lies in how satellites estimate where underwater volcanic mountains might be located. This is achieved by detecting slight changes in the distance between the satellite and the surface of the ocean, which is ever so slightly bulged up due to water piling directly above the seamount, sometimes predicting the location about 1 km from where it actually lies.

Why am I out here?

Wed, 01/11/2017 - 11:01am
But the real answer at least for me lies in the fact that as I have bounced through six decades of life and entered my seventh, a time when so many would argue that they have “seen it all,” I increasingly realize how little I have actually seen, experienced and learned.
