Takabva kure kure kubva ku "Makungwa Akanyarara"

Iyi blog yakatanga kubuda Ocean Noise blog kubva kuOcean Conservation Research

Zvinoshamisa kuti vangani vanhu vari mumunda wesainzi yegungwa uye kuchengetedza chikwereti Jacques Cousteau sekurudziro yerudo rwavo rwegungwa. Panguva iyo TV yemavara yakanga ichitamira muimba yekutandarira yeAmerica Cousteau yakanga ichipa inoshamisa uye inoyevedza trove yezvisikwa psychedelia kushamisa mafungiro edu. Pasina Cousteau's Self-Contained Underwater Breathing Apparatus (SCUBA) uye mapikicha emubatsiri Luis Marden zvingava zvakaoma kufungidzira kuti kufambira mberi kwesainzi yegungwa (kana kuti mamiriro enyanza) kwaizova kupi iko zvino. Kuti vanhu vazhinji vakakwezvwa kuti vade gungwa nenzira yezvipo zvaCousteau ufakazi hwetapuro iyo muoni mumwe anogona kuva nayo papasi.

Nehurombo akapotsa kapfungwa kamwechete: Nekugadzira basa rake rine mukurumbira pasi perubhuriki ye“Nyika Yakanyarara” chikamu chakakosha chekuongorora zvipenyu mugungwa chakatanga kunonoka. Zvinoitika kuti nepo paine yakakura ruvara pallet pakati peiyo biota inogara mu epipelagic kana nzvimbo yezuva mugungwa (200m uye pamusoro), izvo zvinopindirana mukati memvura yose yemvura ndeyekuti maonero akanaka "anotonga nzvimbo." Tichifunga kuti zvisikwa zvakawanda zvemugungwa zvinogara mumvura ine mhepo ine mhepo uye rima rakakwana kana rakazara uko kuoneka kuri kushoma, zvingangoita kuti huwandu hweacoustical adaptation mugungwa hauna kunyatsoongororwa.

Zvinonyadzisa zveizvi ndezvekuti isu tichingori kuwana mazano nezve acoustic sensitivities yehupenyu hwemugungwa, mazhinji maindasitiri, ekutengeserana, uye echiuto kuita negungwa afambira mberi pasi pemafungiro asiriwo ekuti gungwa i "Nyika Yakanyarara," uye uko iyo precautionary musimboti. yakatsvairwa parutivi kuti zvibatsire.

Chokwadi kufarirwa kwe“Nziyo dzeHumpback Whale” uye kuongorora kwekutanga kwedolphin bio-sonar kwakaunza vanhu vazhinji kuti vakurumidze pamhuka yedu yegungwa “hama inoziva,” asi kunze kwehove dzakazara dzerabhu. audiometry basa rakaitwa na Art Popper naRichard Fay, kunzwa kuduku zvikuru - uye zvichida kunyanya kukosha, zvishomanana zvehupenyu soundscape zvidzidzo zvakaitwa vachifunga nezvehove. Ikozvino zvave kuwedzera kuoneka kuti kunyangwe zvipenyu zvemugungwa zvinotsamira pakunzwisisa kwenzwi - uye zviri kukanganiswa neruzha rwunogadzirwa nevanhu.

Kuongorora kwechangobva kubudiswa muna Nature Science Reports inoburitsa kuti ruzha rwekufambisa rwunokanganisa kukura kwe embryonic uye mwero wekupona kwetsuro dzegungwa ne20%. Pakati pemamwe mabasa, mhuka idzi dzinochengeta koral yakajeka kubva kune algae - basa rakakosha rinopa ese ezvimwe zvinonetsa kwezvakatipoteredza izvo koral iri kutambura.

Ruzha pacharwo runogona kuva chiratidzo chenzvimbo dzine hutano dzecoral reef - sezvo nzvimbo dzekugara dzine hutano dzakatetepa neruzha rwezvipenyu. Pepa rakaburitswa munguva pfupi yapfuura mu Marine Ecological Progress inoratidza kuti ruzha rwezvinhu zvipenyu chiratidzo chehutano hwematombo uye kusiyana-siyana uye inoshanda senzira yekufambisa yemhuka dzingada kugara munharaunda. Ruzha rwakanaka, rwakakora, uye rwakasiyana siyana rwebiology runobereka ruzha rwakasiyana rwebiology. Asi kana iyi ruzha rwebhaibheri rwakavharwa neacoustical "smog" ipapo ichavanzwa kubva kune vatsva vanotora.

Chokwadi zvinorehwa neizvi maererano nekureba kwenguva refu kwemaindasitiri ruzha zvinosvika kure. Nepo vazhinji veindasitiri nemauto ruzha mitigations dzakanangana nekudzivirira kufa kwakaipisisa kwemhuka dzemugungwa, kana hove dzisina kudzivirirwa nemhuka dzisina mutsipa uye nzvimbo dzadzo dzakakundwa nekuderera kwenguva refu kubva kune yakaderera-inovhiringidza ruzha mhedzisiro inogona kuipa: Iyo biologically "Nyika Yakanyarara" ine ruzha rwemaindasitiri chete. ruzha rwokunzwa.
