External carapace and pereopod exoskeleton of the Dungeness crab megalopae (a) in its undamaged form (b, c) and with dissolution presence ranging from mild (Stage 1; d) to severe (Stage 2; e, f) patterns showing similarity in the structural damages (g) or exposed crystals (h). Indicated is the scale of the measurements (μm). The undamaged megalopae originated from the offshore or northwards habitats characterized by low ∆Ωcal,60 vertical gradients, while the most severely affected megalopae came from the nearshore or coastal habitats with steep ∆Ωcal,60 conditions.

Dungeness crab larvae already showing effects of coastal acidification – “We found dissolution impacts to the crab larvae that were not expected to occur until much later in this century”

23 January 2020 (NOAA) – A new NOAA-funded study has documented for the first time that ocean acidification along the US Pacific Northwest coast is impacting the shells and sensory organs of some young Dungeness crab, a prized crustacean that supports the most valuable fishery on the West Coast. Analysis of samples collected during a […]

Australia bushfires from the air: before and after images show scale of devastation

By Naaman Zhou 16 January 2020 (The Guardian) – More than 10.7m hectares of land have burnt so far in Australia’s bushfires – larger than the total area of South Korea, or Portugal, and 1.3 times the size of Scotland. The ongoing and unprecedented bushfire crisis has spread across six states and multiple months. In New South Wales alone, the […]

Record summer heat in Alaska wiped out at least 100,000 Kuskokwim salmon in Bristol Bay – “I’ve never seen a salmon that is still ocean-bright acting in such a way”

By Isabelle Ross 15 January 2020 DILLINGHAM, Alaska (Alaska Public Media) – The sun beat down relentlessly on Bristol Bay this summer, heating up the rivers and lakes where millions of sockeye salmon returned to spawn. July was the region’s hottest month on record, and in some rivers, that heat was lethal. Tim Sands, an […]

Australia fire smoke will complete a full circuit of Earth, NASA says

14 January 2020 (BBC News) – Smoke from the massive bushfires in Australia will soon circle the Earth back to the nation, says NASA. Massive infernos have raged along the nation’s east coast for months, pushing smoke across the Pacific. NASA said plumes from blazes around New Year’s Day had crossed South America, turning skies […]

On 1 January 2016 and 2 January 2016, 6,540 common murre carcasses were found washed ashore near Whitter, Alaska, translating into about 8,000 bodies per mile of shoreline — one of the highest beaching rates recorded during the mass mortality event. Photo: David B. Irons

Huge “hot blob” in Pacific Ocean caused mass starvation in largest seabird die-off – “The magnitude and scale of this failure has no precedent”

By Michelle Ma 15 January 2020 (UW News) – The common murre is a self-sufficient, resilient bird. Though the seabird must eat about half of its body weight in prey each day, common murres are experts at catching the small “forage fish” they need to survive. Herring, sardines, anchovies and even juvenile salmon are no […]

Estimated number of animals killed in Australia bushfires rises to more than one billion – “Events like this may well hasten the extinction process for a range of species”

8 January 2020 (University of Sydney) – Professor Chris Dickman has revised his estimate of the number of animals killed in bushfires in NSW to more than 800 million animals, with a national impact of more than one billion animals. Several weeks ago Professor Dickman, from the University of Sydney’s Faculty of Science, estimated that 480 […]

As many fires are still burning in Australia, a regular GLOBE Observer (Glenn Evans in Coogee, New South Wales, about 10 km/6 miles southeast of Sydney), has been taking consistent clouds observations from the same location over the last few weeks, sometimes multiple observations on the same day. In this short video, you can see a compilation of their ground observations in December 2019, facing west and south alongside satellite imagery from the same day taken by the MODIS instrument on the Aqua satellite. Notice the sky coloration when heavy smoke plumes are visible in the satellite image, as well as the days when there is both haze and other types of clouds in the sky. Video: NASA GLOBE Observer

A megafire measuring 1.5 million acres forms in Australia as bushfires merge – “It is too late to leave”

By Andrew Freedman 10 January 2020 (The Washington Post) – Australia’s bushfire crisis worsened Thursday night into Friday as hot, dry and windy conditions redeveloped across the country’s hard-hit southeast, causing two large blazes to merge into one. The new “megafire” measures about 1.5 million acres, about the size of the state of Delaware or […]
