An Antarctic Mission to Recover a Robot’s Data

"We found that extreme winds in the Southern Ocean have increased by approximately 1.5 metres per second or 8 per cent over the last 30 years. Similarly, extreme waves in this same region have increased by 30 centimetres or 5 per cent. Generally, winds are increasing at a faster rate than the waves."But it is happening elsewhere, oceanically:
"In addition to the increases in the Southern Ocean, extreme winds have also increased in the equatorial Pacific and Atlantic, and the North Atlantic by approximately 0.6 metres per second over the 30 year period."The period covered is 1985-2018, and the study used data from 31 satellites in total, comprising over 4 billion measurements, which is impressive.
"[Established] 1910. Inactive since 1978. Approx. 15 m (50 ft) round cast iron tower with lantern, painted white. The active light (focal plane 146 m (479 ft); white flash every 15 s) is on a 4 m (13 ft) cylindrical fiberglass tower standing in front of the historic lighthouse."Pictures below, and a video!
"The lighthouse is built from special wedge shaped clay bricks that were fired especially for this lighthouse. The lantern room is fabricated from fibreglass.And here are the pictures:
One of only a handful of brick lighthouses in Australia, the lighthouse is unique as the bricks have never been rendered or painted, making it a distinctive day mark."
"In color and composition, Ultima Thule resembles many other objects found in its area of the Kuiper Belt. It's very red - redder even than much larger, 1,500-mile (2,400-kilometer) wide Pluto, which New Horizons explored at the inner edge of the Kuiper Belt in 2015 - and is in fact the reddest outer solar system object ever visited by spacecraft; its reddish hue is believed to be caused by modification of the organic materials on its surface."There's still more to learn - the New Horizons spacecraft that flew by Ultima Thule is still sending back data, and will continue to send back data into the year 2020.
"It wasn’t until the turn of the 20th century that a Russian microbiologist demonstrated the potential for anaerobic bacteria to cause dolomite to form from minerals in ocean water, a process called biomineralization. Since then, researchers have found that in modern environments, biofilms — containing photosynthetic microbes and the slimy organic matrix that they excrete for their home (exopolymeric substances) — in highly evaporative pools of salty water can provide a surface on which dolomite can nucleate and grow."

"1993. Active; focal plane 45.5 m (149 ft); white light occulting three times every 8 s. 38 m (125 ft) fluted round cylindrical white concrete tower with a rounded top; the light is displayed through a horizontal window at the top. 500 mm lens. 1-story keeper's house nearby."
"Rolph Payet of the United Nations Environment Program said the "historic" agreement linked to the 186-country, U.N.-supported Basel Convention means that countries will have to monitor and track the movements of plastic waste outside their borders.And the USA couldn't sign this?
The framework "is historic in the sense that it is legally binding," Payet said. "They (the countries) have managed to use an existing international instrument to put in place those measures."
Farmers stand to be greatly affected by changes in the climate, necessitating adaptive responses, yet little is documented on how U.S. Midwestern farmers understand and perceive climate change adaptation. Eight focus groups with 53 Michigan farmers were conducted in 2011–12 to better understand the following: 1) what do farmers think about the relationship between climate change and agriculture, 2) what differentiates normal weather-related management from climate change adaptation actions, and 3) how do farmers understand the term “climate change adaptation.” Farmers expressed skepticism at global climate change yet conveyed specific details about the local changes in climate they are experiencing on their farms. They were not able to clearly define the term “climate change adaptation” but did note specific adaptive actions they have already implemented. The farmers explained that nonclimate factors were of more concern to them when making management decisions, and they showed reactive (not proactive) actions toward adaptation. Farmers noted that any action they take has to address their specific situation, suggesting that generalized adaptation actions and language might not resonate with them. Building on quantitative surveys conducted by others, the findings in this paper contribute to ongoing efforts to more effectively assess farmers’ perceptions related to climate change adaptation and to use that understanding to promote education, outreach, research, and public policies to more proactively address the consequences posed by climate change.
Although temperature trends received attention, most farmers across the focus groups noted changes in precipitation as the most consequential changes for their operations, a concern of farmers across the Midwest (Morton et al. 2015). Michigan farmers noted that, recently, rain events have increased in severity and occurrence. In this region, rainwater represents a critical resource even for those using irrigation. Changes in rainfall thus have tremendous consequences for farm production. One farmer highlighted the dramatic change farmers across the region have experienced in recent years, recounting that “We talked about variations in the weather and precipitation, well in the time that I’ve been farming—this past growing season and the 2009 growing season, were as opposite as I have ever seen in my whole career.” Others mentioned the dramatic variation they see: “This last year, at least down where I live, we went 33 days without a drop of rain. And then we got dumped on with four or five inches all at once. So you go through these dry spells and then huge rain events, and I think that’s more of a change from what we used to see.” Another farmer simply stated, “We’re getting heavy spring rains, four to five inches, that we didn’t use to have before on a regular basis.”
"There is a feeling that the Freedom Caucus may be on the wane in the House, but it's on the ascendency in the West Wing," said one Republican senator, who requested anonymity to discuss colleagues' frustration with Mulvaney.
A second GOP senator said, "He's a former member of the Freedom Caucus, and he's used to saying no."
A third Senate Republican said there's "frustration" that Mulvaney and his ally Russ Vought, the acting White House budget director, are willing to settle for a yearlong continuing resolution to fund the government instead of negotiating a new spending deal with Democrats.

"1918. Active; focal plane 49 m (161 ft); three white flashes every 20 s; in addition, a spotlight (JCG-4968) illuminates the Ogon Bae reef to the south. 18 m (59 ft) octagonal cylindrical concrete tower with lantern and gallery, rising from a 1-story concrete keeper's house. Entire lighthouse is white."Also according to the Directory, this is one of Japan's "Famous 50" lighthouses. It's not hard to figure out why it's on that list.
" “It is a chondritic stone meteorite, composed mainly of silicon, iron and magnesium,” the UCR said in a statement." (UCR = University of Costa Rica)
