Hoʻolauna

ʻO ka moʻo RIV-F5 kahi ADCP ʻelima-kukui i hoʻokuʻu hou ʻia. Hiki i ka ʻōnaehana ke hāʻawi i ka ʻikepili pololei a hilinaʻi hoʻi e like me ka wikiwiki o kēia manawa, ke kahe ʻana, ka pae wai, a me ka mahana i ka manawa maoli, i hoʻohana pono ʻia no nā ʻōnaehana ʻōlelo aʻo waikahe, nā papahana hoʻoili wai, ka nānā ʻana i ke kaiapuni wai, ka mahiʻai akamai, a me nā lawelawe wai akamai. Ua lako ka ʻōnaehana me kahi transducer ʻelima-kukui. Hoʻohui ʻia kahi kukuna kani waena 160m hou e hoʻoikaika i ka hiki ke hahai i lalo no nā wahi kūikawā e like me nā wai me ka nui o ka sediment, a ke loaʻa nei hoʻi ka ʻikepili laʻana i ka ʻikepili pololei a paʻa.

ʻOiai i loko o kahi wai paʻakikī me ka turbidity kiʻekiʻe a me ka wikiwiki o ke kahe ʻana, hiki nō i kēia huahana ke loaʻa kahi hana maikaʻi loa, kahi e hoʻohālikelike ʻia me nā huahana like honua maikaʻi loa, ʻo ia ke koho maikaʻi loa no ka ADCP kiʻekiʻe, hana kiʻekiʻe a me ke kumukūʻai kūpono.

Palena ʻenehana

Hiʻona

ʻO ka ʻenehana acoustic papa mua a me ka maikaʻi i hōʻoia ʻia o ka ʻoihana koa;

Ua hoʻokomo pū ʻia ka mea hoʻololi ʻelima kukuna me kahi kukuna kani waena mai 160m ka laulā, i hoʻohana kūikawā ʻia no nā wai me ka nui o ka sediment;

Mālama maʻalahi me kahi ʻōnaehana kūloko paʻa a hilinaʻi hoʻi;

Ka hiki ke hoʻouka i ka ʻikepili hopena ana i ka kikowaena pūnaewele i kuhikuhi ʻia;

ʻOi aku ka hoʻokūkū o ke kumukūʻai i hoʻohālikelike ʻia me ka hana like ʻo ADCP ma ka mākeke;

Hana paʻa, hana nui like a me ka palena e like me nā huahana like

ʻO ka ʻenehana lawelawe kūpono i kākoʻo ʻia e nā ʻenekinia loea akamai, e hāʻawi ana i nā mea āu e pono ai i ka wā o ke ana ʻana i loko o ka manawa pōkole loa me ka pane wikiwiki. Me ke kākoʻo loea mai ka Institute of Acoustics of the Chinese Academy of Sciences, ua hoʻokuʻu ʻo Seahawk Plus i kahi moʻo ʻelima-beam RIV-F5 o nā profiler wikiwiki o ke kahe Doppler acoustic. Hoʻohana ka ʻōnaehana i ke kumumanaʻo Doppler acoustic e hoʻopuka i ka wikiwiki pololei o ke kahe, ka nui o ke kahe, ka pae wai a me ka ʻikepili mahana ma ka manawa maoli ma ka pūnaewele, e hāʻawi ana i ka ʻikepili pololei a hilinaʻi hoʻi no nā ʻōnaehana ʻōlelo aʻo waikahe, nā papahana hoʻoili wai, ka nānā ʻana i ke kaiapuni wai, ka mahiʻai akamai a me nā lawelawe wai akamai. Ua lako ka ʻōnaehana me kahi transducer ʻelima-beam, e hoʻohui ana i ke kukuna bathymetric waena me ka laulā hohonu 160m, e hoʻoikaika ana i ka hiki ke hahai i lalo no nā kaiapuni wai kūikawā e like me ke one kiʻekiʻe, e hoʻolilo ana i ka ʻikepili laʻana i ʻoi aku ka pololei a me ka paʻa. Ma muli o ka ʻenehana maikaʻi a paʻa a me ka hana mākeke maikaʻi loa o ka moʻo RIV, ua lilo ʻo RIV-F5 i hanauna hou loa o nā huahana ADCP ʻelima-beam ma hope o ka hana hou ʻenehana. ʻOiai i loko o nā wai paʻakikī me ka wai ʻūlū a me ka wikiwiki o ke kahe ʻana, hiki nō i ka huahana ke hana maikaʻi, hoʻohālikelike ʻia me nā huahana honua maikaʻi loa o ke ʻano like, a ʻo ia ke koho maikaʻi loa no ka ADCP kiʻekiʻe, hana kiʻekiʻe a me ke kumukūʻai kūpono.
