Abstract The biological carbon pump has been estimated to export ∼5–15 Gt C yr−1 into the deep ocean, and forms the principal deep-sea food resource. Irregular, intense pulses of particulate organic carbon (POC) have been found to make up about one-third of the overall POC fluxes at a long-term deep-sea research station influenced by coastal upwelling of the California Current, Station M (34°50′N, 123° W, 4000 m depth). However, the drivers of these pulses have been challenging to quantify. It h...

Abstract The upper ocean stratification and circulation in the Bay of Bengal (BoB) plays a key role in the northward propagating monsoon intraseasonal oscillation during the months of June–August. This region is highly influenced by strong, seasonal atmospheric forcing and the oceanic circulation is characterized by dominant mesoscale variability and strong horizontal gradients in salinity and temperature during the monsoon period. Given the role of the ocean in the monsoon circulation, it is im...

Abstract The Chukchi Ecosystem Observatory (CEO), a mooring array of subsurface oceanographic instruments, was established on the northeast Chukchi Sea continental shelf to obtain time-series measurements of physical, biogeochemical, and biological parameters. A sequential sediment trap was deployed on a CEO mooring 8 m above seafloor to measure export fluxes of chlorophyll a (chl a), microalgal cells, zooplankton fecal pellets, total particulate matter (TPM), particulate organic carbon (POC), a...

Abstract Benthosema pterotum is one of the most abundant myctophids and an important species link in the food web between producers and consumers in the continental shelf of the southern East China Sea (ECS). This study used R/V Ocean Researcher 1 and 5 to investigate the spatial distribution of B. pterotum larvae and the associated environmental factors affecting the continental shelf of the southern ECS between 2006 and 2017. A generalized additive model (GAM) was used to evaluate potential ha...

Abstract Chemosymbiotic micro- and macro-fauna related to cold-seep sites were recovered in the Palmahim Disturbance (PD), offshore Israel, during EU EUROFLEETS2 SEMSEEP Cruise, by box-coring and Remotely Operated Vehicle (ROV) dives. No live macrofauna was identified in the collected sediments, with the exception of the seep-related crustacean Calliax lobata (de Gaillande and Lagardere, 1966). Numerous Calliax claws testify the past colonization of these soft bottoms by several generations of t...

Abstract Time-lapse photography provides a sview of the seafloor at timescales that make it possible to recognize behaviors and activity of often slow-moving abyssal fauna. Most behavioral studies have focused on mobile animals; sessile benthic fauna have largely been overlooked. We combed through 30 years of time-lapse camera data from Station M, a long-term study site on the abyssal plain off the coast of California, to survey behaviors of sponges and benthic cnidarians. The sessile fauna of t...

Abstract The calanoid copepod Calanus finmarchicus is one of the most abundant and ecologically important species of the zooplankton assemblage of the North Atlantic Ocean and occupies a pivotal position in the pelagic food web. This study used metabarcoding analysis (high throughput DNA sequencing of target gene regions) to examine the diversity of the copepod gut content, including both eukaryotic and prokaryotic components of the diet and microbiome. Zooplankton samples were collected during ...

Abstract The Southwest Monsoon Current (SMC) in the Bay of Bengal (BoB) and prominent eddies surrounding it, in particular, an anticyclonic eddy (AE) to the southeast and a cyclonic eddy (Sri Lanka Dome, SLD) to the east of Sri Lanka, were investigated using field observations, numerical simulations, satellite imagery, laboratory experiments and theoretical studies. The field campaigns were conducted in 2015 and 2018, respectively, in conjunction with the Air-Sea Interactions in the Northern Ind...

Abstract This study examines the applicability of the two-component mixing model in one dimension (depth) to published depth profiles of DOC concentrations and Δ14C values from hydrographic Station M (34°50′N, 123°00′W). We have rederived the two-component model assuming DOC exhibits stable conservative tracer properties and compared it to a model that includes reactivity and radioactive decay. We used 14C*, the fractionation- and decay-corrected concentration of 14C atoms in DOC or DIC, as a ne...

Abstract Observations of the upper 200 m of the strongly stratified Bay of Bengal reveal a host of interleaving layers of watermass properties. The features appear as isopycnal spice anomalies and form multiple, parallel, ∼ 10 m thin layers, that are coherent over horizontal scales of 30–80 km. They are coincident with anomalies in density stratification and in some cases, with the vertical shear of horizontal velocity, but are not aligned with isopycnals. The cross-isopycnal slopes of these pro...
