了解西北大西洋沿岸海洋的热平衡和相关的温度变化，对于了解气候变化的影响，例如海洋变暖将如何影响渔业管理，具有重要意义。大陆架边缘附近的热平衡特别复杂，在那里，陆架断裂锋内的跨大陆架温度梯度使海气通量异常与海洋平流的竞争影响复杂化。我们回顾了与西北大西洋大陆架和陆坡热平衡相关的大气和海洋过程，强调了热平衡的尺度依赖性。然后，我们使用海洋观测站倡议（OOI）先锋阵列的数据，以证明在南部新英格兰大陆架断裂的热平衡尺度依赖，以及阵列捕捉多尺度海洋过程的能力。2015年5月至2016年4月在OOI先锋阵列测量的海气热通量的累积效应与实际温度变化的比较表明，平流过程在大陆架断裂附近的整体热平衡中的重要性。作者：Ke Chen，Glen Gawarkiewicz，
Knowledge of heat balance and associated temperature variability in the Northwest Atlantic coastal ocean is important for understanding impacts of climate change such as how ocean warming will affect the management of fisheries. Heat balances are particularly complicated near the edge of the continental shelf, where the crossshelf temperature gradients within the shelf-break front complicate the competing influences of air-sea flux anomalies versus ocean advection. We review the atmospheric and oceanic processes associated with heat balance over the Northwest Atlantic continental shelf and slope, with an emphasis on the scale-dependent nature of the heat balance. We then use data from the Ocean Observatories Initiative (OOI) Pioneer Array to demonstrate heat balance scale dependence at the southern New England shelf break, and the capability of the array to capture multiscale ocean processes. Comparison of the cumulative effects of airsea heat fluxes measured at the OOI Pioneer Array from May 2015 to April 2016 with the actual temperature change shows the importance of advective processes in overall heat balance near the shelf break.
