Mary Sears: advancing ocean intelligence [Women’s History Month]
We are so fortunate to have Catherine Musemeche celebrate the life and significant contributions by Mary Sears to our field in the book Lethal Tides: Mary Sears and the Marine Scientists Who Helped Win World War II – now, it is our turn to elevate these details in our classrooms, our textbooks, and elsewhere.

Note to AP and Fox News: A Storm Hit California, Not an Atmospheric River
An atmospheric river is a plume of moisture that often shows up well on Satellite images over large oceans. If I see one associated with a storm, I know that it will likely be a very wet one with increased rainfall. There are a few famous ones as well, like the Pineapple Connection which will sometimes bring tropical air from the Equatorial Pacific into a storm approaching the U.S west …
Blue skies and cloud cover at sea – via quilt
After leaving JOIDES Resolution, I knew I wanted to pull together a data visualization that not only documented the daily Sky/Cloud measurements, but also as a shout-out to the kindergarten teacher that turned her students into mini-scientists observing the world around them, and to the Second Mate from JR Expedition 390 who took the time to explain to the kids (and to me!) his daily weather observations and for responding to all the questions.
Eagle Island Ice Cap, Antarctica Loses its Snowcover in 2023
Eagle Island Ice Cap in Sentinel image from Feb. 19, 2023 illustrating only small patches of snowcover left, 5-10% of ice cap. On February 19, 2023 Eagle Island Ice Cap, Antarctica has less than 10% snowcover. This is less snowcover than observed even after the period of record warm weather over the Antarctic Peninsula in February 2020. Temperature when the all time Antaractica temperature record was set at Esperenza Base. …

Volcan Peteroa Glaciers Argentina/Chile Fragment During Snow Cover Free Summers
Volcan Peteroa glaciers in Sentinel images from March 2016 (below) and March 2023 (above). This illustrates fragmentation, 50% area loss, and a new lake formation. All the result of repeated snowcover free glaciers. For an alpine glacier to survive it must remain mostly snowcovered throughout the year, even at the end of the summer. This is one reason for the majesty of glaciated mountains, they shine brightly even in summer. …

Women in Ocean Science [Women’s History Month]
This post originally was supposed to be focused on a collection of profiles of women in ocean sciences available online. But in working to celebrate our successes, and keeping in mind this year’s theme for International Women’s Day 2023 of #EmbraceEquity, I couldn’t just celebrate the accomplishments – I had to include the challenges these amazing women have faced along the way and still face today.

Snowcover Free Glaciers Generates Fragmenting in Central Andes, Chile
Snowcover free glaciers in the Central Andes in 2014 ad 2023 Landsat images. The ongoing fragmentation and retreat is evident at Point A-H, see closeup details below. The glacier as Point B has melted away, At Point G and H glacier tributaries have separated from the Norte Cipreses Glacier in the valley below. At Point D-F expanding bedrock areas amidst glacier driving further fragmentation. Glaciers at Point A and C …

Bird update February 2023
Click to enlarge February has zipped by, but then again it’s a short month. I’ve continued birding intensively this month, so I’ll provide another update like I did last month. I’ve racked up 71 species this month, and pushed my 2023 total up to 77 (from January’s ending total of 66). The past few days have been very productive, as unseasonably warm temperatures have drawn north some early birds, such …

Framing an oceanography course around the Ocean Decade Challenges
The UN Ocean Decade Challenges acts as an excellent bridge between the traditional oceanographic topics with the science behind our ocean system, while highlighting solutions that incorporate sustainability, diversity, technology, and disciplines outside of STEM.

Announcing Stitch Your Ocean Science 2023
An exciting addition this year is that Stitch Your Ocean Science 2023 has been endorsed as an Ocean Decade Activity by the United Nations Decade of Ocean Science for Sustainable Development! We hope this encourages even more international participation for our global ocean.
