The temporal and spatial variability of oceanographic properties in Potter Cove was analysed for the 2010–17 summer periods. This was linked with meteorological parameters and sea ice. The water column structure presented significant differences in turbidity between two areas (away from and closer to the Fourcade Glacier). The recent retreat has been transforming it into a land terminating glacier. Therefore, correlations obtained between oceanographic properties near the glacier and meteorological parameters reveal that atmospheric conditions are the main forcing of the Potter system, in agreement with previous studies. Also, high turbidity values within deeper waters in 2013 and 2014 were probably related to resuspended glacial sediment input into the cove. Interannual variability observed in the local parameters was connected to ENSO and SAM, reflecting a larger connection with ENSO, mainly in longer timescales. Colder waters during the 2010 and 2016 El Niño phases could be related to lower air temperature. In summer 2010 during a negative SAM phase, colder, more saline and low turbid waters were observed. Alternatively, in 2012 during La Niña and positive SAM, warmer, fresher and more turbid conditions were found with high vertical stratification. Finally, during 2015 (positive SAM), warmer and low salinity waters were observed.

2010 年至 2017 年夏季波特湾水文特性的年际变化

分析了 2010-17 年夏季期间波特湾海洋学特性的时空变异性。这与气象参数和海冰有关。水柱结构在两个区域（远离和靠近Fourcade Glacier）之间呈现出显着的浊度差异。最近的撤退已将其转变为陆地终止冰川。因此，在冰川附近的海洋学特性与气象参数之间获得的相关性表明，大气条件是波特系统的主要强迫因素，与之前的研究一致。此外，2013 年和 2014 年较深水域的高浊度值可能与重新悬浮的冰川沉积物输入海湾有关。在当地参数中观察到的年际变化与 ENSO 和 SAM 相关，反映了与 ENSO 的更大联系，主要是在更长的时间尺度上。2010 年和 2016 年厄尔尼诺阶段的较冷水域可能与较低的气温有关。在 2010 年夏季，在 SAM 负相期间，观察到了更冷、更多盐分和低浊度的水域。或者，在 2012 年拉尼娜和正 SAM 期间，发现了更温暖、更新鲜和更混浊的条件，具有高度的垂直分层。最后，在 2015 年期间（正 SAM），观察到了温暖和低盐度的水域。垂直分层高的条件下发现了更新鲜和更混浊的条件。最后，在 2015 年期间（正 SAM），观察到了温暖和低盐度的水域。垂直分层高的条件下发现了更新鲜和更混浊的条件。最后，在 2015 年期间（正 SAM），观察到了温暖和低盐度的水域。
