德國HYDRO-BIOS公司--多通道沉積物捕獲器
Multi Sediment Trap
多通道沉積物捕獲器的設(shè)計(jì)主要用于對相對垂直顆粒流較大的湖泊、大陸架和水棲環(huán)境的沉積物的自動采集。在北極、南極、熱帶、亞熱帶等環(huán)境中，經(jīng)過無數(shù)次的長期野外操作，已經(jīng)證明了它的可靠性。這款儀器不需要很重的固定線纜，它在較小的船上也可以很容易地安置和收回。多通道沉積物捕獲器的控制裝置可以執(zhí)行為期一年多的時(shí)間依賴性工作。為了防止捕獲到的沉積物從收集筒的上部被沖走，每個(gè)收集器在開口處都安裝一個(gè)可拆卸的塑料網(wǎng)格，捕獲器內(nèi)部完全不含金屬。當(dāng)多通道沉積物捕獲器的采集瓶不工作時(shí)，它們與周圍環(huán)境是隔離的。在布放和回收操作期間，收集筒底部是開放的，允許水流自動流過收集筒腔體。
整體框架材質(zhì)為鈦合金，完全抗腐蝕；整個(gè)系統(tǒng)由3節(jié)長時(shí)間鋰電池供電。根據(jù)不同的需求，不同多通道沉積物捕獲器的收集瓶數(shù)量可以是6、12、24：
豪華型：
豪華型多通道沉積物捕獲器通過PC機(jī)上的一個(gè)OceanLab軟件進(jìn)行預(yù)編程，允許用戶實(shí)時(shí)（年、月、日、時(shí)、分）對每個(gè)收集瓶的采樣間隔單獨(dú)預(yù)先設(shè)定，從1分鐘至8760小時(shí)。豪華型采樣器可通過增加各種參數(shù)的不同傳感器進(jìn)行升級，數(shù)據(jù)存儲器容量可達(dá)4M。

德國HYDRO-BIOS公司多通道沉積物捕獲器國內(nèi)應(yīng)用案例
1、水產(chǎn)養(yǎng)殖領(lǐng)域研究：

MST12多通道沉積物捕獲器和Multi Limnos自動水樣采集器共同參與了山東某大型水產(chǎn)養(yǎng)殖企業(yè)海參養(yǎng)殖區(qū)水體和沉積物之間營養(yǎng)物質(zhì)循環(huán)的研究，獲得了極其珍貴的數(shù)據(jù)，為今后餌料的投放建立了非?？茖W(xué)的數(shù)學(xué)模型，大大降低了企業(yè)的養(yǎng)殖成本。
2、海灣沉積動力學(xué)研究：

德國HYDRO-BIOS公司MST24多通道沉積物捕獲器參與了海洋局羅源灣沉積動力學(xué)科研項(xiàng)目。羅源灣位于福建省沿海東北部，閩江口以北約50公里，是全國少有的天然深水港灣，可全天候靠泊30萬噸輪船。羅源灣具備建造東方大港的條件，從“十一五”期間開始，羅源灣成為福建省重點(diǎn)建設(shè)的港口。羅源灣在行政區(qū)劃上隸屬福州市，北岸屬羅源縣，南岸屬連江縣。根據(jù)海峽西岸經(jīng)濟(jì)區(qū)規(guī)劃，列為福州港的深水外港。羅源灣在福建省、乃至中國港口的發(fā)展中有著非常重要的地位，對它的研究也勢在必行?？蒲腥藛T將MST24長期坐底式布放在羅源灣，成功捕獲到了大量極具代表性的自然沉積物，為羅源灣沉積動力學(xué)的研究提供了真實(shí)可靠的數(shù)據(jù)。
