Tachokera patali kwambiri kuchokera ku "Nyanja Yopanda Phokoso"

Blog iyi idawonekera koyamba Ocean Noise blog yochokera ku Ocean Conservation Research

Ndizodabwitsa kuti ndi anthu angati omwe ali pantchito ya sayansi ya nyanja ndi kasungidwe kabwino ka Jacques Cousteau monga kudzoza kwa chikondi chawo cha panyanja. Pomwe TV yamtundu idasamukira kuchipinda chochezera chaku America Cousteau adapereka chiphaso chodabwitsa komanso chopatsa chidwi chachilengedwe alireza kusokoneza malingaliro athu. Popanda Cousteau's Self-Contained Underwater Breathing Apparatus (SCUBA) ndi zithunzi za wothandizira Luis Mbuye zingakhale zovuta kulingalira kumene kupita patsogolo kwa sayansi ya nyanja (kapena mkhalidwe wa nyanja) kukanakhala pakali pano. Mfundo yakuti anthu ambiri anakopeka kuti akonde nyanja chifukwa cha zopereka za Cousteau ndi umboni wa mmene wamasomphenya mmodzi angakhudzire dziko lapansi.

Tsoka ilo adaphonya mfundo imodzi yaying'ono: Polemba ntchito yake yotchuka kwambiri pansi pa rubriki ya "Dziko Lachete” Mbali yofunika kwambiri yofufuza zachilengedwe za m’nyanjayi inayamba mochedwa kwambiri. Zikuoneka kuti pali phale lalikulu lamitundu pakati pa biota yomwe ikukhala mu epipelagic kapena kuwala kwa dzuwa m'nyanja (200m ndi pamwambapa), chomwe chimagwirizana m'mbali yonse yamadzi ndikuti malingaliro omveka "amalamulira chisa." Poganizira kuti zamoyo zambiri zam'nyanja zimakhala m'madzi aphokoso komanso mdima wandiweyani kapena wathunthu komwe siziwoneka bwino, ndizotheka kuti mitundu yosiyanasiyana yamayendedwe am'nyanjayi sinazindikiridwe.

Chochititsa manyazi cha izi ndikuti ngakhale tikungomva zakumveka kwa zamoyo zam'madzi, zochitika zambiri zamafakitale, zamalonda, ndi zankhondo ndi nyanja zapita patsogolo chifukwa cha malingaliro olakwika akuti nyanja ndi "Dziko Lopanda Chete," komanso pomwe mfundo yodzitetezera. yachotsedwa chifukwa chakufunika.

Zachidziwikire kutchuka kwa "Nyimbo za Humpback Whale” komanso kufufuza koyambirira kwa ma dolphin bio-sonar kunapangitsa anthu ambiri kufulumira pa “abale athu ozindikira” zanyama zam'madzi, koma pambali pa nsomba za lab. audiometry ntchito yochitidwa ndi Art Popper ndi Richard Fay, kumva pang'ono - ndipo mwinamwake chofunika kwambiri, zochepa kwambiri zamoyo mawonekedwe maphunziro achitidwa poganizira za nsomba. Tsopano zikuwonekeratu kuti ngakhale zamoyo zam'madzi zam'madzi zimadalira kamvekedwe ka mawu - ndipo zikukhudzidwa ndi phokoso lopangidwa ndi anthu.

Kafukufuku waposachedwa wasindikizidwa mu Malipoti a Sayansi Yachilengedwe amawulula kuti phokoso lotumizira limasokoneza kukula kwa kalulu wam'madzi ndi kupulumuka kwa akalulu am'nyanja ndi 20%. Mwa zina, nyamazi zimasunga ma coral ku algae - ntchito yofunikira yopatsa zovuta zina zonse zachilengedwe zomwe ma coral akuvutika.

Phokoso lokha likhoza kukhala chizindikiro cha malo abwino a matanthwe a m'mphepete mwa nyanja - monga momwe malo okhalamo athanzi amakhala odzaza ndi phokoso lachilengedwe. Pepala lofalitsidwa posachedwa mu Kupita patsogolo kwa Zachilengedwe Zam'madzi akusonyeza kuti phokoso lachilengedwe ndi chizindikiro cha thanzi la matanthwe ndi mitundu yosiyanasiyana ndipo limakhala ngati njira yoyendera nyama zomwe zingafune kukhazikika m'derali. Phokoso labwino, lowundana, komanso losiyanasiyana lachilengedwe limabweretsa phokoso lamitundumitundu. Koma ngati phokoso lachilengedweli litabisika ndi "utsi" wa acoustical ndiye kuti lidzabisika kwa olembedwa atsopano.

Zoonadi zotsatira za izi ponena za phokoso lokhalitsa la mafakitale ndilotali kwambiri. Ngakhale phokoso lalikulu la mafakitale ndi lankhondo kuchepetsa zimayang'ana kwambiri popewa kufa koopsa kwa nyama zam'madzi, ngati nsomba zosatetezedwa ndi zamoyo zopanda msana ndi malo omwe amakhalamo zigonja pakuwonongeka kwanthawi yayitali kuchokera kuphokoso laling'ono losokoneza zotsatira zake zitha kukhala zoyipa kwambiri: "Dziko Lachete" lachilengedwe lokhala ndi phokoso la mafakitale. phokoso kumva.
