海底強流 的英文怎麼說

海底強流
英文
bottom current-
Cryptic species have been found in a wide range of marine organisms ; with majority of them are benthic invertebrates. in contrast, marine holoplanktons are thought to have lower diversity and slow speciation due to their strong dispersal potential. this paper reviewed studies on cryptic species and speciation in marine holoplankton. based on findings in 38 studied taxa, it was concluded that : 1 ) cryptic species are pervasive in marine holoplankton, suggesting holoplankton speciation was more active than previously thought ; 2 ) current morphospecies diversity is untenable to reflect true species diversity in marine holoplankton ; 3 ) geographic isolation may facilitate cryptic speciation of marine holoplankton. however, contribution of allopatric speciation is still questionable ; 4 ) ecological speciation may be the prevailing speciation mode in marine holoplankton. cryptic speciation in marine holoplankton is paradoxical, because rapid speciation under strong gene flow is countertuitive. solution of this paradox will help us gain deep insights of marine speciation and biodivesity
隱種廣泛存在於各類海洋生物中，尤其是底棲無脊椎動物.然而，海洋終生浮游生物由於具有較強的擴散能力，往往被視為生物多樣性低、物種形成慢.本文就海洋終生浮游生物隱種與物種形成的研究作一綜述.基於研究的38個種類，結果表明: 1 ）海洋終生浮游生物普遍存在隱種，其物種形成要比想象得快; 2 ）由於引種的廣泛存在，形態種生物多樣性無法反映海洋終生浮游生物真正的物種多樣性; 3 ）地理隔離有助於海洋終生浮游生物隱種的形成，但異域物種形成的作用仍值得商榷; 4 ）生態物種形成很可能是海洋終生浮游生物物種形成的主流模式.海洋終生浮游生物強基因流下快速的物種形成有悖于生物進化常理，解決該悖論將有助於我們對海洋物種形成和生物多樣性的理解According to their space position, the seismic features of shallow gas in this region can be divided into three groups : ( 1 ) features in the stratum : acoustic blanket, acoustic curtains, acoustic turbidity, irregular strong top reflection boundary, and phase pull - down in both flanks ; ( 2 ) features of the seabed : seabed pockmark and giant sunken pit ; ( 3 ) features in the seawater column : acoustic plumes, cloudy turbidity and point - line - type reflection
該區的淺層氣地震特徵按空間位置分為3大類： （ 1 ）地層中的特徵：聲學空白、聲學幕、聲學擾動、不規則強反射頂界面、兩側相位下拉； （ 2 ）海底面的特徵：海底麻坑、大型塌陷坑； （ 3 ）海水層中的特徵：聲學羽流、雲狀擾動、點劃線反射。In the interim from highstand systems tract to transgressive systems tract, faulting is violent in the basin, different kind of fluids coming from dissimilar position of lithosphere enter into synsedimentary faults served as a place fluids mixed to form ore - bearing hydrocarbon alkali - fluids
在從高水位體系域向海侵體系域的盆地相迅速轉化時，盆地內斷裂構造活動強烈，斷裂溝通不同部位的熱水流體，使成礦烴堿流體沿斷裂上升，在海底沉積成礦。Concentrations of total suspended matter ( ctsm ) is unanimous with observational data and other scholars " researching results. the distribution of ctsm is higher along coast than other areas there is a tongue - like zone with high ctsm from north to southeast. the transport simulation result reveals that sm can spread to the okinawa trough for enough sea water mixing in winter. but in summer. sm can not traverse the big water barrier of kushino for different circulation character. this difference is probably related to the shifting n - s monsoon
懸浮體輸送表明，在冬季，懸浮體除了在陸架上發生擴散外，由於海水的強烈混合作用和環流的季節性變化，部分中、底層懸浮體可擴散至沖繩海槽甚至西太平洋;在夏季，由於海水層化及夏季環流特徵，懸浮體基本不能穿越黑潮這一水障，這一差異可能是由於季風和不同環流特徵所引起的。Located 3 km below the ocean ' s surface and 120 km offshore, the deposit is beyond the reach of humans and all of the construction has to be completed by robots working against strong underwater currents, sub - zero temperatures and extreme wind and wave conditions
這座天然氣田位於海底三公里處，離挪威陸地有一百二十公里遠；光靠人力很難成事，因此埋設管線的工作只好交給機器人，由它們來對抗海流、酷寒、強風與大浪。分享友人
