The first time scientists explored deep in the Indian Ocean, they found a new species of glowing squid. Now researchers who departed from South Africa last Monday with even better equipment are hoping for similar success.

In 2009, the scientists collected some 7,000 samples, including the newly discovered squid, which has light-producing organs that it uses to attract its prey. Researchers aboard the RRS James Cook are taking along special cameras for photographing the ocean floor — something they did not have last time.

“We don’t know much about the deep sea community,” Aurelie Spadone, a sea specialist with the International Union for Conservation of Nature (IUCN), said in a telephone interview on Nov. 21 before setting out. “It would be very surprising if we don’t find something like a new species.”

The trip is focused on learning more about how deep sea fishing is affecting marine life along seamounts — peaks rising from the floor of the southern Indian Ocean.

Carl Gustaf Lundin, director of IUCN’s Global Marine and Polar Program, said many of the species that live around seamounts grow and reproduce slowly, so overfishing can severely affect their populations.

科學家首度探測印度洋深處時,他們發現了一種身體會發光的新品種烏賊。如今,上週一從南非啟程、裝備更好的研究人員,希望取得類似的成功。

二○○九年,這些科學家蒐集到約七千個樣本,其中包括該種新發現的烏賊,牠擁有能製造光線的器官用來吸引獵物。「庫克船長號」上的研究人員,將帶著拍攝海床的特殊攝影機,這是他們上次沒有的東西。

國際自然保護聯盟(IUCN)的海洋專家歐海莉‧史巴登十一月二十一日啟程前接受電話訪問時說:「我們對深海(生物)群落所知不多」。他說:「如果我們沒找到一些新物種,將令人很訝異。」

這趟行程著重在更進一步了解深海捕魚正如何影響沿著海洋山脈—從南印度洋海床升起之山峰—的海洋生命。

IUCN全球海洋與極地計畫主任卡爾‧古斯塔夫‧倫丁說,許多棲息在海洋山脈周遭的物種生長與繁殖速度緩慢,因此過度捕撈足以嚴重影響牠們的總數。
