View of Halema‘uma‘u at Kīlauea summit - July 2 2021
View of Halema‘uma‘u at Kīlauea summit - July 2 2021A view looking north into Halema‘uma‘u on July 2, 2021. Although eruptive activity has paused at the summit of Kīlauea, HVO geologists still monitor the lava lake and summit area regularly. Lava lake surface depths remain the same over the past few weeks.

Photomicrograph from a raccoon found sick and euthanized in TexasPhotomicrograph from a raccoon (Procyon lotor) found sick and euthanized in Texas, US. (A) A cluster of schistosome ova are present in the pancreas. Ova are thin-shelled and are not operculated. Each viable egg contains a miracidium (arrows). The ova are surrounded by infiltrates of eosinophils, macrophages, and lymphocytes. H&E stain.

U.S. River Conditions, April to June 2021
This is an animation showing the changing conditions of USGS streamgages from April 1, 2021 to June 30, 2021. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring indicates it is flooding.

Eyes on Earth Episode 53 - Remapping Canada's Fire History
Eyes on Earth Episode 53 - Remapping Canada's Fire HistoryMapping fire perimeters is important work. It guides post-fire restoration efforts, fire mitigation strategies, and helps track of trends in burn severity over time. In the past, many of Canada’s fire agencies relied heavily on techniques like sketch mapping, which estimate burned area without exact measurements.
