Floating substance possibly iron oxide, but GNWT wants to make sure.
Coral reefs worldwide are experiencing a severe bleaching event, with satellite data indicating extreme heat stress across all oceans, threatening near-complete mortality for many corals.
A NOAA Ocean Exploration-led team has discovered what appears to be evidence of a large gas seep at a depth of nearly 1.4 miles (2,300 meters) along the Aleutian Trench. The discovery was found in data collected during the Seascape Alaska 1: Aleutians Deepwater Mapping expedition.
Increase in sediments such as iron could change quality of water sources for local communities such as Kobuk and Kivalina. The impact on animals and plants are unknown and researchers are aware of potential changes in the food web in the future.
Permafrost is ground that stays frozen year round; the permafrost in interior Alaska also has massive wedges of actual ice locked within the frozen ground. When that ice melts, the ground surface collapses and forms a sinkhole that can fill with water. Thus, a thermokarst lake is born. At first glance, Big Trail looks like any lake. But look closer and there's something disturbing the surface: bubbles.
If upwelling starts a month earlier than usual, the amount of oxygen, already low, has to last until the fall when storms promote mixing which adds oxygen back into the system. As of late September this year, upwelling is still occurring and low levels of oxygen are still persisting.
A failing breakwater in Conception Bay South in Newfoundland shows just how ill-prepared most places are for the climate crisis.
Ruben Henry won't ever forget the day the Chandalar River ran red along the banks of Arctic Village. It was the talk of the tight-knit, Brooks Range town, and no one had could remember it ever happening before.
Halobacteria thrive in bodies of water with high levels of salt. The salinity inside the Kealia Pond outlet area is currently greater than 70 parts per thousand, twice the salinity of seawater. Maui's drought is likely contributing to the situation. Normally Waikapu Stream feeds into Kealia Pond and raises water levels there, but Wolfe said that hasn't happened in a long time.
