Do you think of models, liposuction and facelifts when you hear "plastic surgery"? You may be surprised to hear that aesthetic procedures makeup a relatively small portion in the field of PRS. Here we discuss how the specialty originated with a focus on the first patients.
The near-bottom water on the U.S. Northeast continental shelf provides a critical cold-water habitat for the rich regional marine ecosystem. This 'cold pool' preserves winter temperatures, even when waters elsewhere become too warm or salty during the summer. The U.S. Northeast coastal ocean has experienced accelerated warming in recent years, compared to the global average. Now, scientists using salt as a tracer are investigating how much the influx of salty offshore water onto the continental shelf contributes to the observed 'erosion' of the seasonal cold pool. This paper provides the first evidence for a seasonal salinification of the cold pool on the US Northeast continental shelf, as consistently observed in the multi-year mooring record of the [Ocean Observatories Initiative] Coastal Pioneer Array.
