Hoʻopilikia ka hana ʻana i ka moana i ka pōʻino o ke kaiapuni a hiki ke loaʻa i kahi cascade o nā hopena maikaʻi ʻole i nā mea kanu a me nā holoholona.
"ʻO ka hōʻeha kino a i ʻole ka make ʻana mai ka hāʻule ʻana, ka hoʻoulu ʻana o ka walaʻau, a me ka piʻi ʻana o ka turbidity nā ala nui e hiki ai i ka dredging ke hoʻopili pololei i nā mammals moana," wahi a kahi ʻatikala ma ka ICES Journal of Marine Science.
"ʻO nā hopena pili ʻole o ka dredging i nā mammals kai mai nā loli i ko lākou ʻano kino a i ʻole kā lākou mea pio. Hoʻololi ʻia nā hiʻohiʻona kino, e like me ka topography, ka hohonu, nā nalu, ke kai, ka nui o ka sediment particle a me ka hoʻopaneʻe ʻana o ka sediment concentrations, e hoʻololi ʻia e ka dredging, akā hiki mai nā loli ma muli o nā hanana haunaele e like me ke kai, nā nalu a me nā ʻino.
Hiki i ka Dredging ke loaʻa i ka hopena pōʻino i ka mauʻu kai, e alakaʻi ana i nā loli lōʻihi o ke kahakai a hiki ke hoʻopilikia i nā kaiāulu o uka. Hiki i nā lau nahele ke kōkua i ka pale ʻana i ka ʻinoʻino o kahakai a lilo i ʻāpana o nā haʻihaʻi e pale aku i ke kahakai mai nā ʻino. Hiki i ka ʻauʻau ʻana ke hōʻike i nā moena kai i ka ʻāʻī ʻana, hoʻoneʻe ʻia a luku ʻia paha.
ʻO ka mea pōmaikaʻi, me ka ʻikepili kūpono, hiki iā mākou ke kaupalena i nā hopena maikaʻi ʻole o ka dredging moana.
Ua hōʻike ʻia nā haʻawina me nā kaʻina hoʻokele kūpono, hiki ke kaupalena ʻia nā hopena o ka hoʻoulu ʻana i ke kai i ka masking kani, nā loli ʻano pōkole a me nā loli i ka loaʻa ʻana o nā mea pio.
Hiki i nā mea ʻaelike hoʻoheheʻe ke hoʻohana i nā puʻu nalu mini a Frankstar e hoʻomaikaʻi ai i ka palekana o ka hana. Hiki i nā mea hana ke komo i ka ʻikepili nalu manawa maoli i hōʻiliʻili ʻia e ka mini wave buoy no ka hoʻomaopopo ʻana i nā hoʻoholo hele/ʻaʻole hele, a me ka ʻikepili kaomi wai lepo i hōʻiliʻili ʻia no ka nānā ʻana i nā pae wai ma ke kahua o ka papahana.
I ka wā e hiki mai ana, hiki i nā mea ʻaelike dredging ke hoʻohana i nā lako ʻike moana a Frankstar e nānā i ka turbidity, a i ʻole ka akaka a i ʻole ka opaque o ka wai. ʻO ka hana ʻauʻau ʻana e hoʻoulu i ka nui o ka sediment, a ʻoi aku ka kiʻekiʻe ma mua o nā ana turbidity maʻamau i loko o ka wai (ʻo ia hoʻi ka piʻi ʻana o ka opacity). He lepo ka wai ʻāhuehue a hūnā i ka mālamalama a me ka ʻike ʻia o nā mea kanu a me nā holoholona moana. Me ka Mini Wave buoy ma ke ʻano he hub no ka mana a me ka hoʻohui ʻana, hiki i nā mea hoʻohana ke komo i nā ana mai nā mea ʻike turbidity i hoʻopili ʻia i nā moorings akamai ma o Bristlemouth's open hardware interface, e hāʻawi ana i nā hana plug-and-play no nā ʻōnaehana ʻike moana. ʻOhi ʻia ka ʻikepili a hoʻouna ʻia i ka manawa maoli, e ʻae i ka turbidity e nānā mau ʻia i ka wā o ka hana dredging.
