使用安装在自主着陆器系统上的图像增强（ISIT）相机检查了大西洋东北部970至4，800米深度海底生物产生的天然生物发光（不受人为干预的机械刺激）。在没有诱饵的情况下，观察到很少或没有发光，但有诱饵存在，与深度有显着的反比关系，Log 10（1 +事件数h−1）= 1.7627-0.3235深度（km）（r2 = 0.8158，P < 0.001），表明4 km处的平均事件数为2.6 h−1，1 km处为28 h−1。在一个地区，在CA。在碳酸盐岩和珊瑚土丘附近1 km深度，平均值为133次事件h−1，远高于预测。在这个生物发光热点中，观察到52-483个事件h-1，包括移动发光目标和将发光材料的斑块释放到诱饵周围的水中，使得有时诱饵周围的整个区域被照亮，持续时间为分钟。在深海深处，发光比在佛得角附近的热带东北大西洋类似深度报告的要少得多。发光的来源无法确定，但在最活跃的地区与存在的鳗鱼Synaphobranchus kaupii，虽然本身不发光可能有刺激发光的猎物生物，如介形虫（Vargula norvegica）。
Natural bioluminescence (that not mechanically stimulated by human intervention) produced by organisms on the seafloor of the northeast Atlantic ocean between 970 and 4,800 m depth was examined using an image intensifying (ISIT) camera mounted on an autonomous lander system. In the absence of bait little or no luminescence was observed but with bait present there was a significant inverse relationship with depth, Log10 (1 + number of events h−1) = 1.7627–0.3235 depth (km) (r2 = 0.8158, P < 0.001) indicating an average of 2.6 events h−1 at 4 km and 28 h−1 at 1 km. But in an area at ca. 1 km depth near carbonate and coral mounds the mean was 133 events h−1, much higher than predicted. In this bioluminescent hot spot 52–483 events h−1 were observed including moving luminescent targets and release of patches of luminescent material into the water around the bait so that on occasions the whole area around the bait was illuminated persisting on a time scale of minutes. At abyssal depths, luminescence was much less than reported at similar depths in the tropical NE Atlantic off Cape Verde. The sources of luminescence could not be determined but in the most active areas were associated with presence of eels Synaphobranchus kaupii which although themselves not luminescent may have stimulated luminescence from prey organisms such as ostracods (Vargula norvegica).
