Abstract With characteristics of large amplitude and strong current, internal solitary wave (ISW) is a major hazard to marine engineering submarine navigation; it also has significant impacts on ecosystems fishery activity. Among the world oceans, ISWs are particular active in northern South China Sea (SCS). In this spirit, SCS Internal Wave Experiment been conducted since March 2010 using subsurface mooring array. Here, we report an extreme ISW captured 4 December 2013 with maximum 240 m...
Abstract Deep water circulation in the Luzon Strait, which connects Pacific deep with South China Sea throughflow, is investigated using a set of oceanographic observations combined results from three numerical experiments. Both situ and model show overflow Strait. Their suggest that first flows into Strait through Bashi Channel (1.2 Sv, 1 Sv = × 10 6 m 3 s −1 ) Taltung Canyon (0.4 Sv), then turns southward along Trough, finally enters primarily two gaps Heng‐Chun Ridge. Overall, mean...
Abstract Changes in the Atlantic Meridional Overturning Circulation, which have potential to drive societally-important climate impacts, traditionally been linked strength of deep water formation subpolar North Atlantic. Yet there is neither clear observational evidence nor agreement among models about how changes influence overturning. Here, we use data from a trans-basin mooring array (OSNAP—Overturning Subpolar Program) show that winter convection during 2014–2018 interior basin had...
Abstract Tropical Cyclones (TCs) are devastating natural disasters. Analyzing four decades of global TC data, here we find that among all TC-active basins, the South China Sea (SCS) stands out as particularly difficult ocean for TCs to intensify, despite favorable atmosphere and conditions. Over SCS, intensification rate its probability a rapid (intensification by ≥ 15.4 m s −1 day ) only 1/2 1/3, respectively, those rest world ocean. Originating from complex interplays between astronomic...
Abstract The Luzon Strait, with its deepest sills at the Bashi Channel and Trough, is only deep connection between Pacific Ocean South China Sea (SCS). To investigate deep-water overflow through 3.5 yr of continuous mooring observations have been conducted in Trough. For first time these enable us to assess detailed variability from SCS. On average, along-stream velocity maximum about 120 m above ocean bottom, reaching 19.9 ± 6.5 23.0 11.8 cm s−1 central respectively. measurements can be...
Abstract The role of mesoscale eddies in modulating the semidiurnal internal tide (SIT) northern South China Sea (SCS) is examined using data from a cross-shaped mooring array. From November 2013 to January 2014, an anticyclonic eddy (AE) and cyclonic (CE) pair crossed westward SIT beam originating Luzon Strait. Observations showed that, because current stratification modulations by pair, propagation speed mode-1 sped up (slowed down) 0.7 m s −1 (0.4 ) within AE’s (CE’s) southern portion. As...
Abstract Although observational efforts have been made to detect submesoscale currents (submesoscales) in regions with deep mixed layers and/or strong mesoscale kinetic energy (KE), there no long-term observations subtropical gyres, which are characterized by moderate values of both layer depths and KE. To explore dynamics this oceanic regime, two nested mesoscale- submesoscale-resolving mooring arrays were deployed the northwestern Pacific countercurrent region during 2017–19. Based on 2...
Deep western boundary current (DWBC) was observed for the first time by an array of 6 meter moorings southeast Zhongsha Islands in South China Sea (SCS) deep basin during period from August 2012 to January 2014. In mean, DWBC SCS flows southwestward with core velocity 2.0 cm/s and a volume transport 1.65 Sv (1 = 1 × 106 m3/s). Its temporal variability is dominated intraseasonal fluctuations around 90 days. The main axis DWBC, characterized low temperature core, tends not shift 90-day fluctuation.
Phytoplankton are the basis of primary production and play important roles in regulating energy export marine ecosystems. Compared to other regions, chromophytic phytoplankton considerably understudied Bay Bengal (BOB). Here, we investigated community structure spatial distribution BOB by using RuBisCO genes (Form ID rbcL). High throughput sequencing rbcL revealed that diatoms, cyanobacteria (Cyanophyceae), Pelagophyceae, Haptophyceae, Chrysophyceae, Eustigamatophyceae, Xanthophyceae,...
Abstract The intensity of deep‐ocean mixing critically shapes the global overturning circulation, but energy cascade participating in elevated above rough topography remains poorly understood. Using 350‐day moored observations, triggered by eddy‐topography interactions is for first time revealed deep South China Sea. observations show bottom‐intensified near‐inertial wave (NIW) pulses during periods eddy occurrences. Eddy‐induced NIWs appear to catalyze nonlinear wave‐wave interactions,...
Abstract Water‐mass transports in the vast and seemingly quiescent abyssal ocean, basically along topographically‐guided pathways, play a pivotal role Earth's climate. The pulse of circulations can be taken with observations at topographic choke points. Yap‐Mariana Junction (YMJ) is exclusive point through which Lower Circumpolar Deep Water (LCDW) enters Philippine Sea. Here, we quantify LCDW transport its variability based on mooring YMJ Mariana Trench (MT). flows northward toward Sea as an...
Abstract Cold and dense water from the North Pacific Ocean that spills through Luzon Strait, only deep conduit between South China Sea (SCS) Ocean, renews deep-water mass, modulates hydrographic biogeochemical cycles, drives abyssal overturning circulations in SCS. The variability of this key oceanic process, however, has been poorly studied, mainly due to a lack sustained observations. A comprehensive observational program started 2009 provided 12 years continuous time series velocity...
Hadal ocean biosphere, that is, the deepest part of world's oceans, harbors a unique microbial community, suggesting potential uncovered co-occurring virioplankton assemblage. Herein, we reveal assemblages Challenger Deep, comprising 95,813 non-redundant viral contigs from surface to hadal zone. Almost all dominant in zone were unclassified, potentially related Alteromonadales and Oceanospirillales. 2,586 auxiliary metabolic genes 132 different KEGG orthologous groups mainly carbon,...
Abstract Internal solitary waves (ISWs) typically exhibit a strong tendency to preserve their waveforms and amplitudes upon collision, but this preservation breaks down when two ISWs obliquely interact. Although oblique wave‐wave interactions have been frequently observed in the oceans worldwide studied extensively through theoretical research satellite imagery, fundamental underwater dynamics spatiotemporal evolution of these remain poorly understood. This study presents detailed...
Abstract Water‐mass properties and circulation in the deep abyssal Philippine Sea are investigated using repeatedly occupied full‐depth hydrographic data. The water‐mass, Lower Circumpolar Deep Water (LCDW), is captured. After crossing Yap Mariana Junction, LCDW spreads to Parece Vela Basin, southern part of Shikoku Minami‐Daito northern with its upper interface sinking from ∼4,000 m ∼5,000 m. Blocked by Central Basin Fault, cannot penetrate further southward into Basin. An current across...
Abstract The complex behaviors of internal solitary waves (ISWs) in the Andaman Sea were revealed using data collected over a nearly 22-month-long observation period completed by two moorings. Emanating from submarine ridges northwest Sumatra Island and south Car Nicobar, types ISWs, referred to as S- C-ISWs, respectively, identified measurements, S-ISWs generally found be stronger than C-ISWs. observed C-ISWs frequently appeared multiwave packets, accounting for 87% 43% their episodes,...
Abstract A train of subsurface mesoscale eddies (SMEs) consisting two cyclones and anticyclones was observed in the northeastern South China Sea (NESCS) 2015 by a mooring array. In contrast to widely reported surface-intensified eddies, SMEs had weak surface signals but showed maximum velocity at ∼370 m with magnitude 17.2 cm s −1 . The generally propagated westward speed ∼4.3 , which resulted distinct ∼120-day-period oscillations moored time series. Based on concurrent velocity,...
