德國HYDRO-BIOS公司——多通道沉積物捕獲器
Multi Sediment Trap

多通道沉降物捕集器的設(shè)計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)證明了此沉降物捕集器的可靠性。這款沉降物捕集器不需要很重的固定線纜，沉降物捕集器在較小的船上也可以很容易地安置和收回。多通道沉降物捕集器的控制裝置可以執(zhí)行為期一年多的時間依賴性工作。為了防止沉降物捕集器捕集到的沉降物從收集筒的上部被沖走，沉降物捕集器的每個收集器在開口處都安裝一個可拆卸的塑料網(wǎng)格，沉降物捕集器內(nèi)部完全不含金屬。當(dāng)多通道沉降物捕集器的采集瓶不工作時，它們與周圍環(huán)境是隔離的。在沉降物捕集器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。

 整個沉降物捕集器系統(tǒng)由3節(jié)長時間鋰電池供電。根據(jù)不同的需求，不同多通道沉降物捕集器的收集瓶數(shù)量可以是6、12、24：豪華型多通道沉降物捕集器通過PC機上的一個HYDRO-BIOS軟件進(jìn)行預(yù)編程，允許用戶實時（年、月、日、時、分）對沉降物捕集器的每個收集瓶的采樣間隔單獨預(yù)先設(shè)定，從1分鐘至8760小時。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公司多通道沉降物捕集器國內(nèi)應(yīng)用案例

1、水產(chǎn)養(yǎng)殖領(lǐng)域研究：

MST12多通道沉降物捕集器和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)水體和沉降物之間營養(yǎng)物質(zhì)循環(huán)的研究，獲得了珍貴的數(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多通道沉降物捕集器參與了羅源灣沉積動力學(xué)科研項目。羅源灣位于福建省沿海東北部，閩江口以北約50公里，是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。科研人員將MST24長期坐底式布放在羅源灣，成功捕集到了大量具有代表性的自然沉降物，為羅源灣沉積動力學(xué)的研究提供了真實可靠的數(shù)據(jù)。
