The macrozoobenthos living around two offshore gas platforms, Barbara NW (pB) and Calipso (pC) located in the northwestern Adriatic Sea were investigated for three years after their construction to detect eventual effects due to the platforms. The sampling stations were spaced at increasing distance from the platforms up to 1000 m. Both multivariate and univariate analysis showed an initial defaunation (short-term effect) at pB and within a 120 m radius at pC. A general recovery in terms of abundance, species richness and diversity was observed for the benthic communities after one year. During the third monitoring year a mussel mound developed at both the platforms (longer-term effect) extending up to 30 m from pC, whereas similar soft-bottom communities were found at all the other distances. The geographical position plays an important role in the "timing" of the above effects. Moreover, despite the different environmental features, a 3-year monitoring plan can be effective to evaluate the potential impact on benthic communities of offshore gas platforms in the north-central Adriatic Sea.
在西北亚得里亚海,对两座近海天然气平台(Barbara NW 平台(pB)和 Calipso 平台(pC))周围的大型底栖动物进行了为期三年的调查,以检测平台可能产生的影响。采样站距离平台的距离逐渐增加,最远可达 1000 米。多元和单变量分析均表明,pB 平台出现了初始的动物灭绝(短期影响),而在 pC 平台周围 120 米的范围内也出现了类似情况。一年后,底栖生物群落的丰度、物种丰富度和多样性均呈现出总体恢复的趋势。在第三个监测年,两个平台上都形成了贻贝丘(长期影响),从 pC 向外延伸可达 30 米,而在其他所有距离上都发现了类似的软底群落。地理位置在上述影响的“时间”上起着重要作用。此外,尽管环境特征不同,但三年监测计划可有效评估近海天然气平台对亚得里亚海中北部底栖生物群落的潜在影响。
