“…A tabulated list of commonly used technologies for observing continental shelves is shown in Table . More details of these methods can be found in many references, and we point the reader to Brink and Kirincich () and references therein for an informed and thorough exposition. Two overarching themes are apparent in coastal and shelf sustained observing: (1) complexities of territorial water management, discontinuity and/or disconnected efforts, lack of coordinated historical archiving, changing priorities for coastal waters, and all present challenges to data discovery of existing shelf seas observation, let alone creating of new sustained observing programs; (2) the shorter time and space scales of variability in shallow continental shelf waters and the proximity to land favor the adoption of robotic technologies (gliders, autonomous underwater, and surface vehicles) and land‐based methods (e.g., tide gauges and high frequency radar).…”
