Abstract The Deepwater Horizon (DWH) oil spill in the NE Gulf of Mexico in 2010 was the largest accidental spill globally. During and after the spill, oil was incorporated into marine snow (marine‐oil‐snow or MOS) and sedimented to the seafloor, accounting for ∼21% of the oil released.

ABSTRACT Quantifying where marine organisms are born and subsequently disperse to is essential for fisheries management. Here, we conducted Lagrangian particle tracking of viviparous rockfish (Sebastes spp.) collected in the Southern California Bight over the course of 16 years.

FEATURES OF FISH BEHAVIOR IN THE ACTION ZONE OF MIDWATER TRAWL
Researches in the field of behavior and distribution of fish at different stages of fishing were conducted using midwater trawls in order to increase fishing efficiency, subject to the fact that, besides fish behavior, parameters of midwater trawls and types of trawling affect the efficiency of trawling.

Abstract The biological carbon pump sequesters carbon through passive fluxes of biologically derived carbon, and by active vertical movement of marine organisms. Trophic coupling between pelagic and benthic communities increases the efficiency of the biological carbon pump as less carbon is lost to remineralization.

Driving anchovy larvae by large mesh wings of pair midwater trawl.
Wing meshes of commercial pair midwater trawls for catching anchovy larvae are as large as 360cm at the distal part and 15cm at the proximal part. Echo surveys were made using a 200kHz fish finder to examine if the larvae were driven into the net mouth by the wings of the extremely large meshes or escaped through the meshes.

The Ragfish, Icosteus aenigmaticus Lockington, 1880: A Synthesis of Historical and Recent Records From the North Pacific Ocean and the Bering Sea [PDF]
Knowledge of the distribution and biology of the ragfish, Icosteus aenigmaticus, an aberrant deepwater perciform of the North Pacific Ocean, has increased slowly since the first description of the species in the 1880’s which was based on specimens ...

Shape and Hydrodynamic Characteristics of Canvas Kite for Midwater Trawl.
キャンバスカイトの流体特性を明らかにするために, 形状の異なる5種類のキャンバスカイトの模型を用いて, 0.2から0.5までの4段階の異なるキャンバーと迎角30°から130°の範囲で水槽実験を行った。実験で得られた揚力と抗力から求めた最大揚力係数と最大揚抗比は, I型の反り比0.2と迎角度50°で, それぞれ1.37と2.00であった。また, 簡単な構造の拡網装置としてキャンバスカイトを用いるには, I型が最適形状であるといえた。
