An underwater acoustic recorder was moored off Heard Island from September 2017 through March 2018 to listen for marine mammals. Analysis of data was initially conducted by visual inspection of long-term spectral averages to reveal sounds from sperm whales, Antarctic and pygmy blue whales, fin whales, minke whales, odontocete whistles, and noise from nearby ships. Automated detection of sperm whale clicks revealed they were seldom detected from September through January (n = 35 h) but were detected nearly every day of February and March (n = 684 h). Additional analysis of these detections revealed further diel and demographic patterns.

... Therefore, dryland rivers are dynamic, and regular adjustments to their channel cross-sectional area occur in order to accommodate the prevailing discharge and sediment supply from upstream; these adjustments may evolve in response to longer-term changes in their hydrological and sediment supply (Leopold et al., 1964;Knighton, 1998;Tooth and Nanson, 2000;Larkin et al., 2017a;Nanson and Huang, 2017). Common types of channel-floodplain adjustments in dryland alluvial rivers include: meander migration and development (Block, 2014;Gomes et al., 2023a), new channel formation through progradational or incisional avulsions (Donselaar et al., 2013;Larkin et al., 2017b;van Toorenenburg et al., 2018;Li et al., 2023;Graves et al., 2024), aggradation through sediment deposition (Ralph et al., 2011), and incision through knickpoint (gully) retreat (Pederson et al., 2006;Pearson et al., 2024). ...
