And another Celebrity ship, I believe Mercury, had a similar incident a few seasons back:
Its probably pointless spending money on an autopsy - once its dead you cant bring it back. Though if a few whales are found dead then you conduct them to see if its something that can be prevented.
Pic & article in Spanish here. Willem has a better photo in Part 6 [pic 26] of his Oceanic Trip this year.
There has been a lot of study into why whales don't seem to get out the way of ships. Some thought is that they may purely be 'asleep' at the time, others say they have been made deaf by man. One such article and the research is here.
One nevertheless gets the impression that these events occur more often recently - whether this is really the case or whether it is only the preception via moderm media is another issue.
Has anyone information on the regulations concerning Glacier bay? I heard that the number of ships has initally been more limited and then later increased a bit as it has been found that whales are much less anoyed by the (noise of the?) ships.
I wonder if it also happened to ship retro-fitted like ssBremen(built as Pasteur1939) and ssGolden Odyssey(built as ssShalom)?

it's not the color... whales don't seem to use their eyes for recognition even close up. It's the form signature. Whales and Dolphins use their somar to create a kind of mental image of the shape of something and the form of the bulb could be mistaken for some sort of animal.
quote:Originally posted by Ernst:I doubt it has something to do with the bulb - other than on a 'conventional' bow (which is actually less conventional these days) the animals can be caught on the bulb whereas this is not possible with other geometries. Also whales and dolphins can 'percieve' ships and avoid collisions - this must be something else. (noise - illness - 'sleeping' - whatever)
I agree. The whale could have already been dead or very ill.
A ship is long and it could all be a error of judgement if they go in front of the ship - there is no engine/prop sound.
I know dolphins are attracted to ships they love doing their jumps around the side and bow - it is great to see if you ever get the chance.
quote:Originally posted by Sutho: [..] - there is no engine/prop sound.[..]
Oh, there is a lot of noise coming from ships - everywhere (!) in the ocean - not only near ships (and therefore also at the bow) - the low frequency part can travel hundreds of kilometers - and it is quite loud too.
It is only a theory in the navy that the reason ships hit them is error of judgement by not realising the ship is as big as it is.
I know how sonar works in subs and how far sound travels - the fact is they pinpoint the props to a certain area and know that the props are not coming from the front of the ship.
Perhaps when I said "there is no engine/prop sound" I should have been more specific and said there is no engine/prop sound being radiated/created/transmitted from the bolbous bow of a ship - and made my post long for the benefit of people who only want to understand what is written in English and not bother to think where people are coming from
If people still have trouble understanding what I meant is whales pinpoint the engine prop sound as being X distance away from them, when they swim close to ships it could be an error of judgement thinking that because they are further away from the loud noise that they can move in closer making an error of judgment forgetting where the very front is and how close they are by trying to avoid what is obviously the loudest part of the ship.
maybe as well as writing long posts instead of being quick and brief I should spell it all out like this and give examples and spell words phonetically

Holland America Line received the Conservation Partnership Award for taking the initiative to develop and promote the adoption of whale avoidance measures as the international cruise industry standard. The company’s dedication to protect whales, regardless of its affect on the financial bottom line, is at the forefront of marine mammal conservation among the cruise line industry. Holland America Line has made its avoidance measures and training program available to the public and cruise line industry to promote the adoption of this stewardship practice.
