Researchers from UNSW Sydney have analyzed millions of satellite photos to observe changes in beaches across the Pacific Ocean. The findings, published in Nature Geoscience today (Feb. 10), reveal for the first time how coastlines respond to different phases of the El-Niño-Southern Oscillation (ENSO) cycle…

The USGS has collected and released topographic data that show the erosional effects of the January 2023 storms on the coast for the Santa Cruz region of California…Comparing the data with pre-storm conditions mapped in September 2022 provide “before” and “after” perspectives of the effects of the January storms. These data have been released under USGS Emergency Use Data authorities for data that have immediate or time-sensitive relevance to public health and safety…
