瓶鼻海豚发声信号复杂多样,各种信号在时域上存在较大差距,但频率都集中在超声频带内。通过实验结果分析可以看出,click 声信号长度主要集中在20 μs~30 μs 之间,信号间隔差异较大;不同的声行为下瓶鼻海豚click 声信号的频谱特性基本上是一致的,峰值频率在110~120 kHz 之间,但发声次数有显著不同。喂食和训练时,发出的click 声信号次数较多,而自由游泳和受到惊吓时,发声次数明显减少。另外,实验计算结果也表明,室内环
境下瓶鼻海豚的click 声信号频率峰值比自然环境下低40 kHz 左右,这与Whitlow W L Au 研究结果相一致[8]。本文对自然环境下圈养的瓶鼻海豚发声进行记录与分析,实验结果对于以后开展海豚声学相关研究提供了基础。对click 声信号强度以及频谱特性的细化分析,将是进一步的研究方向。

              组图 安德内斯虎鲸袭击4头抹香鲸
              It was the probably most specacular day I have ever spent on the water so far. Nothing was normal today when we headed out in the morning for our first trip. The flat calm water made it easy for us to find the whales and we had the luck of being surrounded by about 20 Sperm Whales in close range – an unusual amount. Next to those beautiful sightings we had Minke Whales showing up every now and then, getting the people on board excited and we could get some nice ID-pictures.

              The afternoon seemed to become a more difficult trip as the wind was picking up and there were for some reasons less whales around. I saw one Minke Whale feeding close to the surface and people were watching it while waiting for a Sperm Whale to come back to the surface. Suddenly I saw another Minke Whale nearby but my collegues disagreed and insisted it had been something else, maybe an Orca. I looked at the bad picture I had taken in a rush and although the qualitiy is not good at all, it clearly shows a Minke Whale.

              下午似乎成为风拿起旅行更加困难,有一些原因不鲸鱼在。我看到一个小须鲸喂养接近表面,人们看着它在等待一个抹香鲸回到表面。突然我看到一个小须鲸附近的但我的同事不同意,坚持了别的东西,也许虎鲸。我看了看坏的图片我已经匆忙,虽然质量不好,这清楚地表明一个小须鲸。

                But what had my collegues seen then? Our captain said he believed he had seen something moving quick in front of the boat – and having heard that I saw an Orca popping up right behind our boat. The big male surfaced from underneath our boat, swimming enormously fast. I had no chance to take a picture, all I caught was a lot of water and a little bit of whale.

                  The Orcas, a pod of about 7-10 animals swam fast forwards where we suddenly saw a Sperm Whale surfacing. And it was obvious, the Orcas were heading towards this whale. They swam right up to the Sperm Whale and started to harras him, while he started to take off. It didn’t take long and this animal was together with another Sperm Whale. The two whales almost touched each other with the bodies, clearly in defensive behaviour, breathing heavily and we heart lots of clicks from their sonar on our hydrophones. The Orcas disappeared for a while, suddenly we couldn’t see them anymore. The two Sperm Whales were swimming right next to our boat, doing nose-lifting to check the surface with their eyes. The animals seemed very stressed and then we saw the Orcas heading back towards the two Sperm Whales. It took a while until we realised that those Orcas were hunting a third Sperm Whale, which was swimming towards us to join the other two. The three Sperm Whales gathered together, touching each others body 翻译:虎鲸,一群大约7-10动物游得很快了,我们突然看到一只抹香鲸浮出水面。很明显,虎鲸正在走向这条鲸鱼。他们游到抹香鲸和开始哈拉斯他,当他开始起飞。没多久,这种动物是连同另一头抹香鲸。两个鲸鱼几乎触及对方的身体,显然在防御行为,沉重的呼吸,我们的心很多的点击他们对我们的水听器声纳。虎鲸消失了一阵子,突然,我们看不到他们了。两个精子鲸游泳旁边的船,做鼻子升降用眼睛检查表面。动物似乎非常强调,然后我们看到逆戟鲸回到两个抹香鲸。它花了一段时间,直到我们意识到那些虎鲸猎杀三分之一巨头鲸,这是游向我们加入另外两个。三鲸聚集在一起,彼此接触体。
                  这群虎鲸大概7到10头,它们突然朝一头浮出水面的抹香鲸游了过去,开始骚扰它
                  抹香鲸则在试图摆脱虎鲸,没过一会,它跟另一头抹香鲸会合了,差不多身体都撞在一块
                  虎鲸们消失了一会,这俩抹香鲸则朝着我们船的右侧游动

                    As the Orcas aggressivly passed by one of the Sperm Whales did a rolling maenouvre right underneath our boat. All this happened about 3 meters next to our boat – the Sperm Whales dived without showing the fluke and the Orcas disappeared. We did not see the Orcas again. The Sperm Whales stayed at the surface for a long time, lifting their noses and doing shallow dives every now and then. About 20 minutes later we could watch one Sperm Whale doing a normal dive and the picture of the fluke showes injuries on both fluke tips.

                    20分钟后他们下潜了,这张图可以看到抹香鲸尾巴上的伤

                    About the same time, one of whales breached nearby – maybe the Minke Whale which had joined the spectacular scene all the time and we didn’t see again, or maybe it was one of the Sperm Whales.
                    Marta Acosta Plata, Sperm Whale researcher for Whalesafari since 4 years, couldn’t believe her eyes. “It is not usual that Orcas attack male Sperm Whales in a place like this. Usually Orcas would rather go for mother and calves but not attack in a feeding ground where ther are only males – this is incredibly extraordinairy what we have seen today!”.

                    大约在同一时间,一个附近的–鲸鱼突破也许小须鲸,加入了壮观的场面,所有的时间,我们又没看见,或者也许是抹香鲸。
