Summer temperatures in excess of 52°C, have been measured at the high tide mark in surficial substrates in the exposed areas of an intertidal mudflat in Bahrain. The incoming flood tide may have a temperature as high as 42°C. As a result, large swaths of the upper intertidal zone are barren of living meiofauna (e.g., foraminifera, ostracods, gastropods, and worms) during the hottest months of the year. Samples collected from the intertidal zone in August present only dead assemblages of foraminifera, ostracods, and gastropod shells. Dead assemblages of the foraminifer Peneroplis collected from the upper reaches of the intertidal zone consist largely of juvenile specimens, implying that the living populations, when present, do not reach maturity. The full range of living meiofaunal organisms is only observed in tidal channels that remain submerged during low tide. The presence of a summer dead zone for intertidal meiofaunal organisms is consistent with predictions of climate models that suggest portions of the Arabian Gulf may become too extreme to support eukaryotic life.

在巴林的潮间带滩涂裸露区域中，表层基质的夏季潮汐标记已测出夏季温度超过52°C。传入的洪水潮可能具有高达42°C的温度。结果，在一年中最热的月份中，潮间带上方的大片条带是活的鱼类（如有孔虫，成虫，腹足纲和蠕虫）的稀疏。从八月份的潮间带收集的样品仅显示有孔虫，成虫和腹足动物壳的死亡组合。有孔虫Peneroplis的死组合从潮间带上游采集的鱼主要是幼体标本，这意味着生活中的人口没有成熟。仅在潮汐通道中观察到了整个潮汐生物的生命，这些潮汐通道在退潮时仍被淹没。潮间带动植物的夏季死亡区的存在与气候模型的预测相符，该预测表明阿拉伯海湾的某些地区可能变得过于极端而无法支持真核生物。
