Satellite observations provide valuable information on the rapidly increasing marine heatwaves over the Arctic Ocean, yet current assessments of these events lack reliability because the satellite-based temperature in ice-covered regions heavily relies on ice conditions. Here we compared the marine heatwaves derived from two commonly used satellite...
Mars' north polar ice cap features troughs that cut into the ice, exposing subsurface layers of different brightness and topographic expression. Specifically, these layers represent two different stratum types: lower albedo (higher dust content) marker beds, which protrude out of the wall topographically, and higher albedo (i.e., icier) interbeds,...
Troughs carved into Mars' polar ice cap expose layers of different brightness and topography. These layers can be divided into two strata types: darker, higher dust content marker beds and brighter, lower dust content interbeds. In a companion paper (Pascuzzo et al., 2025, https://doi.org/10.1029/2024JE008377), we measure the topographic protrusion...
