GLOBE students from
Nuuk, Greenland
on board from Nuuk to the Azores studying sound in the Oceans:
Maria Kreutzmann (student), Søren Mortensen
(student) and Uwe Lindholdt (teacher) from the GLOBE high school
in Nuuk took part in the Galathea Expedition from Nuuk to the
Azores.
Photos: Uwe Lindholdt.
Exciting photo and sound report especially about the
sounds of whales (97 MB).
The birds of the Azores (3 MB).
The flora of the Azores (10 MB).

Sound in the Oceans:
Text and sound files: Marianne Helene
Rasmussen, PhD, University of Southern Denmark, took part in the
Galathea Expedition from Nuuk in Greenland to Perth in Australia.
Humpback whale (sound):
The humpback whales sing complicated songs during the
mating season. The whales sing different songs different places
in the world. Humpback whales around Hawaii sing a different song
than the humpback whales close to Australia. This is called
geographic variation. The humpback whale song is the most complex
vocalization in the animal kingdom. The song can be divided into
themes, frases and units. It is only the males singing and they
sing to attract females or to scar the other males.
(Pukkelhval:
Under parringssæsonen synger pukkelhvaler komplicerede sange.
Hvalerne synger forskellige sange forskellige steder i verden.
For eksempel synger pukkelhvalerne omkring Hawaii en sang, mens
pukkelhvaler omkring Australien synger en helt anden sang. Dette
kaldes for geografisk variation. Pukkelhvalsang er den mest
komplicerede lyd i dyreverdenen, det er meget melodisk og kan
inddeles i temaer, fraser og enheder. Det er kun hannerne, der
synger, og man mener, at de synger for at tiltrække hunner og
frastøde eller skræmme de andre hanner).
Brydes whale (sound):
Brydes whale is a baleen whale. Baleen whales make
low-frequency sounds, they can use for communication like to find
a mate for mating. The low frequency sounds are between 100 Hz
– 600 Hz
(Brydes
hval: Brydes hvalen er en bardehval. Bardehvaler laver
lav-frekvente lyde, som benyttes til kommunikation, som f.eks.
til at finde en mage til parring. De lavfrekvente lyde fra brydes
hvalen er mellem 100 Hz – 600 Hz).
Spotted dolphins (sound):
Dolphin use whistles for communication. The fundamental
frequency of the whistles mostly varies between 1 – 20 kHz
(but can go up to 35 kHz).
(Plettede
delfiner: Delfiner bruger fløjt til at kommunikere med.
Fløjtene har oftest en fundamental frekvens mellem 1 kHz –
20 kHz, men kan gå op til 35 kHz).
white-beaked dolphin (sound):
The dolphins use clicks for echolocation. This is to find
their way and to find prey. The clicks contain frequencies up to
250 kHz.
(Hvidnæse
delfin: Delfinerne bruger klikkene til ekkolokalisering, dvs. til
at finde vej og til at finde føde med. Klikkene indeholder
frekvenser helt op til 250 kHz).
Blue whale (sound).
Students from the high school of
Borupgaard Amtsgymnasium
on board from Copenhagen to Nuuk:

The students have created their own
webpage
(in Danish): http://www.galathea.eu/news.php In March they are
going to visite a school in New York
presenting the results from the expedition.
A few weeks later the Galathea
Expedition ship will arive
to New York or Boston, USA.
