Tidepools are not uncommon in Antarctica, but there appear to be no data on the physical environment within polar tidepools and only anecdotal information on their biology. Here we report a high resolution record of temperature in an Antarctic tidepool made over two summers and the intervening winter. During the summer open water season the highest daily mean, and also the maximum temperatures, were recorded during the period of continuous daylight around the summer solstice. This short-term variability of temperature in the tidepool greatly exceeded that in the nearby open ocean, indicating the need for a eurythermal physiology in tidepool biota. In winter the tidepool froze over, the unfrozen water cooled to − 5.5 °C, and freeze concentration increased its salinity to roughly three times normal seawater. A polar tidepool isolated from the sea in winter is probably inimical to many larger marine organisms, which must populate the tidepool afresh each summer.

极端海洋环境：极地潮池中 14 个月的温度记录

潮池在南极洲并不少见，但似乎没有关于极地潮池内物理环境的数据，只有关于其生物学的轶事信息。在这里，我们报告了南极潮汐池在两个夏季和其间的冬季进行的高分辨率温度记录。在夏季开放水域季节，最高日均值和最高温度记录在夏至前后的连续日光期间。潮池中温度的这种短期变化大大超过了附近公海的温度，表明需要潮池生物群中的广热生理学。冬季潮池结冰，未结冰的水冷却至−5.5 °C，结冰浓度使其盐度增加到正常海水的三倍左右。
