Data from the deep-sea mooring Kiel 276 (33${}^{\circ }$N, 22${}^{\circ }$W), 5300 m water depth in the northeast Atlantic, was used to investigate the temporal variability of temperature and currents below the main thermocline (1000 m, 1600 m, 3000 m, 5000 m) in the 30-year period (between 1980 and 2009). Daily averages were the basis to assess the temperature and currents changes, as well as kinetic energy, from annual to decadal and long-term scales. Below the main thermocline, no seasonal signal was identified for both, temperature and currents, during the 30 years. The record-length linear temperature trends at 1000 m and 1600 m are 0.03 ± 0.01 °C year⁻¹ and 0.02 ± 0.02 °C year⁻¹, respectively. The mean currents also intensified within the decades in the entire water column, and as a consequence, the mean kinetic energy increased. The fluctuating kinetic energy increased on a decadal scale only at 1000 m, as a possible consequence of the increase in the strength of Mediterranean Water lenses (MEDDIES) that crossed the mooring site. During the period 2001–2009, six MEDDIES crossed the Kiel 276 site, in addition to the 10 MEDDIES identified earlier during the previous 20 years, between 1980 and 2000 (Siedler et al., 2005). The integral time scales are of the same order in all depths (between 30 to 40 days), indicating that events occur on similar time scales, with mesoscale signals dominating and being present within the entire water column.

深海系泊Kiel 276（33${}^{\circ }$N，22${}^{\circ }$W） 在东北大西洋的水深为5300 m时用于调查在30年期间（1980年至2000年之间）主热跃层（1000  m，1600  m，3000  m，5000  m）以下的温度和洋流的时间变化。2009）。日平均值是评估从年尺度到十年尺度和长期尺度的温度和电流变化以及动能的基础。在主温跃层之下，在这30年中，没有发现温度和水流的季节性信号。记录长度的线性温度变化趋势在1000 米和1600  m为0.03±0.01  ℃，年^-1和0.02±0.02  ℃，年^-1， 分别。在整个水柱中，平均电流也在数十年之内增强，结果，平均动能增加了。波动的动能仅在1000  m处以十年尺度增加，这可能是由于穿过停泊地点的地中海水镜（MEDDIES）强度增加的结果。在2001年至2009年期间，除了1980到2000年之间在过去20年中较早发现的10种药物之外，还有6种药物越过了基尔276号基地（Siedler等人，2005年）。积分时标在所有深度（30到40天之间）都处于相同的顺序，这表明事件以相似的时标发生，中尺度的信号占主导地位，并出现在整个水柱中。
