ICDeep（用于深海研究的图像增强电荷耦合器件）剖面仪被用来测量东、西、中爱奥尼亚海和阿尔及利亚海盆水柱中的深海生物发光动物的密度。一个西向东减少BL densitywasfound.Generalized添加剂modeling被用来调查的季节变化在东部和西部的爱奥尼亚海（NESTOR和NEMO中微子望远镜网站，分别）BL测量在2008年秋季和2009年春季。在西爱奥尼亚海发现了显著的季节效应（p<0.001），在那里，BL密度的深秋峰值出现在500和2400米之间。在东爱奥尼亚海（p=0.07）BL密度没有显着的季节变化。在春季和秋季，东、西爱奥尼亚海水体中的BL密度存在显著差异（p<0.001）。
The ICDeep (Image Intensified Charge Coupled Device for Deep sea research) profiler was used to measure the density of deep bioluminescent animals (BL) through the water column in the east, west and mid-Ionian Sea and in the Algerian Basin. A west to east decrease in BL density was found. Generalized additive modelling was used to investigate seasonal variation in the east and west Ionian Sea (NESTOR and NEMO neutrino telescope sites, respectively) from BL measurements in autumn 2008 and spring 2009. A significant seasonal effect was found in the west Ionian Sea (p<0.001), where a deep autumnal peak in BL density occurred between 500 and 2400m. No significant seasonal variation in BL density was found in the east Ionian Sea (p=0.07). In both spring and autumn, significant differences in BL density were found through the water column between the east and west Ionian Sea (p<0.001).
