This study investigated the changes in concentrations of haloacetic acids (HAAs) and haloacetonitriles (HANs) as disinfection byproducts (DBPs) for different storage times (as long as 20 days) and temperatures (5 to 20°C). A ship's voyage after treatment of its ballast water with active substances was considered. The HAA showed a clear trend of inc...

The relationship between age and oxygen is one that is often assumed in oceanography to be relatively simple. Because oxygen utilization rates are difficult to directly measure in the ocean, it is commonly assumed that the apparent oxygen utilization divided by the water age is a good representation of respiration. Likewise, because of limited tran...

The aim of this study is to determine the acoustic characteristics of sailfin sandfish over a wide frequency range. The acoustic survey was conducted in February, May, and August 2015 off Dokdo, Republic of Korea using EK60 echosounder (18, 38, 70, 120, and 200 kHz) with the mid-water trawls. Target strength (TS) of sailfin sandfish as functions of...

Marine bioluminescence is a unique phenomenon and widely studied around the world. However, information on bioluminescence is scarce in the Indian ocean. This study was carried out to understand the spatial and temporal variations in planktonic bioluminescence off the south coast and the Puttalm Lagoon of Sri Lanka. Planktonic bioluminescence inten...

Based on fine-resolution simulations, we present a case study of the frontogenetic generation of submesoscale flows associated with a convergence field inside an anticyclonic mesoscale eddy in the Kuroshio Extension. The results reveal that the generation of submesoscale flows on the edge of the eddy is closely related to the convergent zone in the...

In order to improve the predictability of winter storm waves in the East Sea, this article explores the use of the ensemble Kalman filter technique for data assimilation in wave modeling. The nested wave model has been established using SWAN along the east coast of Korea to simulate wave transformation and wave dissipation in coastal areas to obtai...

Monsoon droughts are characterized by the weakening of surface winds over the equatorial Indian Ocean and increased upper ocean heat storage, thus providing a sustained heat source for deep convection. This in turn increases rainfall over the eastern equatorial Indian Ocean and weakens the regional Hadley circulations, along with the subsidence of ...

Widely distributed on tidal flats on the west and south coast of Korea, the long arm octopus Octopus minor is one of the important shellfish resources, as well as a key species in the siltymud tidal ecosystem. While several molecular studies have studied the genomes or the molecular phylogenetic relationship of O. minor with other cephalopod member...

—We examined the effects of changing from oxic to anoxic conditions on microbial communities using both biogeochemical and molecular approaches in a semi-enclosed estuary (Jinhae Bay, Republic of Korea). Total microbial activity, represented by oxygen demand in the water column (WOD) or sediment (SOD), revealed that the respective microbial communi...

Ulva are ubiquitous and opportunistic green algae species that easily adapt to various environmental conditions. These algae are responsible for the green tides that cause many environmental and ecological problems in coastal waters. We investigated the physiological responses of Ulva australis under warming, acidification, and eutrophication condi...
