A presentation on Middle Jurassic fossils from the #Kilmaluag Fm of #Skye, Scotland by

Many publications already + images of unpublished material prompted audible wows from the audience. Richard suggests it's time to recognize the deposit as a Lagerstätten.

The Blomstrandbreen glacier has retreated >2 km since 1928 and >3 km since 1861.

Aerial map of Blomstrandbreen with lines drawn on to showing the glacial fluctuations between 1861 and 2006. Data is based on landsat imagery and aerial photographs. It shows that the glacier has retreated over 2 km since 1928 and over 3 km since 1861. Image is from Burton et al. (2016) Marginal fluctuations of a Svalbard surge-type tidewater glacier, Blomstrandbreen, since the Little Ice Age: a record of three surges. Arctic, Antarctic, and Alpine Research, 48: 2, 411-426. DOI: 10.1657/AAAR0014-094 Plot showing the mean distance of the margin of Blomstrandbreen from the LIA maximum in the western channel (black) and the eastern channel (green), using recorded extents between 1861 and 2006. There were surges in the 1920s, 1960s, and 2010s but overall the glacier has retreated over 2 km since 1928 and over 3 km since 1861. Image is from Burton et al.

When images of glacial retreat are posted online it's amazing how many people's gut reaction is "summer vs winter!" without any consideration for latitude + light levels or knowledge of actual glaciers.
#ChristianAslund
#Blomstrandbreen
#Svalbard
The image shows six panes. The top left pane shows the Blomstrandbreen glacier (Svalbard) as photographed in 1928 by the Norwegian Polar Institute labelled "The Arctic, Summer 1928". The middle left pane shows the same glacier as photographed in 2002 by Christian Aslund labelled "The Arctic, Summer 2002". The bottom left pane shows the same glacier as photographed in 2022 by Christian Aslund labelled "The Arctic, Summer 2022". The top right pane is black and labelled "The Arctic, Winter 1928". The bottom right pane is all black and labelled "The Arctic, Winter 2002". The bottom right pane is all black and labelled "The Arctic, Winter 2022". Yes, the labels and panes on the right are added in jest but the topic is serious: overall this glacier has retreated over 2 km since 1928 and over 3 km since 1861.

These two posts made by the same account on X illustrate the dishonesty of #ClimateChangeDeniers:

2023: "The cooling since 2016 has been going as expected..."

Diego Vaz, a curator of fishes here at @nhm-london.bsky.social, just asked me if this Indian eagle-owl (#Bubo bengalensis) on exhibit in the red/green zone was collected by #JohnWick.
Oblique-side view of the owl specimen. There is a blue pencil projecting from the left side of the head to indicate the location of the ear opening and show that the conspicuous feather horns (plumicorns), located on top of the head, are unrelated to the organ of hearing.
