1972 - Ongoing Dove Marine Laboratory Benthic Station M1 (North Sea) Time Series Data

Initiated in 1972, as long term monitoring with station P. M1 was the central station at a historic sludge disposal site in the Central North Sea, approximately 10.5 km away from the English North - East coast, with a depth of 55 m and a muddy sandy sediment. In 1972 and 1973 bimonthly (20 replicates) sampling occurred with sampling decreasing to September and March annually with 5 replicates taken at each occurrence. A 0.1 m2 Van Veen grab was used to collect samples passed over a 0.5 mm sieve and taxon abundance recorded per metre squared (Buchanan and Warwick, 1974). Community stability was seen in the period between 1974 and 1980, which was lost in 1980 - 1983. Changes in species ranking and increases in total numbers and biomass during the latter period.

始于1972年，以P. M1站为长期监测的核心，位于北海中部一历史性污泥处置场地，距离英格兰东北海岸约10.5公里，深度为55米，沉积物为泥质砂。在1972年和1973年，每两个月进行一次（20个重复样本）采样，采样频率逐年降至每年九月和三月，每次采样5个重复样本。使用0.1平方米的Van Veen抓斗，通过0.5毫米筛网收集样本，并按照每平方米记录物种丰度（Buchanan和Warwick，1974）。在1974年至1980年期间观察到群落稳定性，但在1980年至1983年间这种稳定性丧失。在此后期，物种排名发生变动，总数量和生物量有所增加。
