Short summary
Short summary
We distinguished particulate organic carbon (POC) export fluxes out of the nutrient-depleted layer (NDL) and the euphotic zone. The amount of POC export flux at the NDL base suggests that the NDL could be a hotspot of particle export. The substantial POC export flux at the NDL base challenges traditional concepts that the NDL was limited in terms of POC export. The dominant nutrient source for POC export fluxes should be subsurface nutrients, which was determined by 15N isotopic mass balance.

A 3-D model was run for the South China Sea to explore the effects of sea level drop and monsoon wind intensity on glacial patterns of circulation and ventilation. Winter northeasterly monsoon wind intensity governs the volume transport of Kuroshio intrusion through the Luzon Strait, subsequently, the water exchange rate and the mean residence time of water body of the SCS.

This research was done to understand and investigate the roles of Chl-a, PP and sea ice extent in controlling and producing the in-situ measured MSA, SA, HIO3, HOM and aerosol concentrations over the Greenland and Barents Seas. Our results provide strong support to the hypothesis that MSA, SA and small-particle concentrations in the Svalbard area are directly linked to ocean biological activity and sea ice melting during springtime.

Short summary
This study provides comprehensive datasets encompassing seasonal and interannual variations in sulfate and MSA concentration in aerosol particles in the Arctic atmosphere. As oxidation products of DMS have important roles in new particle formation and growth, we focused on factors affecting their variability and the branching ratio of DMS oxidation. We found a strong correlation between the ratio and the light condition, chemical properties of particles, and biological activities near Svalbard.

Short summary
We evaluated the connection between DMS and the formation of aerosol particles in the Arctic atmosphere by analyzing multiple datasets of atmospheric DMS, aerosol particle size distributions and aerosol chemical composition that were collected at Ny-Ålesund, Svalbard (78.5° N, 11.8° E), during April–May 2015. The key finding from this research is that the contribution of biogenic DMS to the formation of aerosol particles was substantial during the phytoplankton bloom period.

An extreme rainfall-producing mesoscale convective system (MCS) associated with the Changma front in south-eastern South Korea was investigated using observational data. The aim of the present study is to analyze and better understand the synoptic and mesoscale environment and the behaviour of the MCS causing natural hazards over South Korea.

Short summary
The anthropogenic nitrogen deposition has led to an increase in nitrate relative to phosphate in the upper oligotrophic waters; however, this anthropogenic nitrogen signal is unclear in the North Atlantic. We analyzed datasets from repeated measurements on meridional and zonal transects in the upper North Atlantic between the 1980s and 2010s and found that the anthropogenic nitrogen signal has been found only in the upper western North Atlantic.
The anthropogenic nitrogen deposition has led to an increase in nitrate relative to phosphate in...
