[1] Using in situ data from 88 cruises from 1987 to 2009 in the East China Sea, downstream nutrient flux (the product of velocity and nutrient concentration) and nutrient transport (integration of flux over a section) by Kuroshio were examined. The presence of a maximum nutrient flux core in the middle layer was confirmed. Seasonal variation in the nutrient flux was not significant and was much...

Abstract Arctic sea ice has been retreating at an accelerating pace over the past decades. Model projections show that Ocean could be almost free in summer by middle of this century. However, uncertainties related to these are relatively large. Here we use 33 global climate models from Coupled Intercomparison Project 6 (CMIP6) and select best capture observed sea-ice area volume northward ocean...

The present paper reviews the geological development of the Faroes part of the NE Atlantic Margin in the Cenozoic Era. The Faroes area is located west of the post-Caledonian rift basin system formed in the Devonian after the collapse of the Caledonian mountains. Tectonic movements and plate reorganizations during several phases have strongly influenced sedimentation and erosion along the Caledo...

More than 2000 measurements of atmospheric and dissolved methane (CH4) were performed in the central and northwestern Arabian Sea as part of the German JGOFS Arabian Sea Process Study during three cruises in March, May/June, and June/July 1997. Mean CH4 saturations in the surface waters of the central Arabian Sea were in the range of 103-107%. Significantly enhanced saturations were observed in...

Brackish water lake is home of peculiar organisms, as its salinity is middle of those of sea and fresh water. Its salinity changes sensitively with sea level, river flow rate and lake topography. Hinuma Lake is one of brackish water lakes in Japan and connects with the Pacific Ocean through a tributary and a major river. Therefore the inflow process of salt water to the lake is very complex. Th...

The Upper Bajocian- Lower Bathonian succession in the Kopet-Dagh Basin of NE Iran represents fluvio-deltaic to turbidite deposits. The Kashafrud Formation provides an excellent opportunity to study the interplay between deep-water sedimentation and syndepositional tectonic subsidence (or uplift) in the region. The effects of these processes caused sea-level changes, variation in depositional se...

New observations of reef accretion from several locations show that in Hawai‘i accretion during early to middle Holocene time occurred in areas where today it is precluded by the wave regime, suggesting an increase in wave energy. Accretion of coral and coralline algae reefs in the Hawaiian Islands today is largely controlled by wave energy. Many coastal areas in the main Hawaiian Islands are p...

The Okhotsk Sea is the southernmost marginal sea that is ice-covered during winter; therefore, it is considered to be an area having sensitive environmental characteristics due to the influence of global warming. In order to detect such environmental changes, monitoring of oceanographic conditions is considered important. However, few monitoring studies have been made in the offshore area of th...

The geographical position of the Arctic front and two branches Polar over Europe was determined during period 1995–2015 using calculated grid fields thermal frontal parameter in troposphere layer 850–700 hPa. It revealed that climatological fronts changed both cold warm periods year comparison with climate data. most recent standard reference 1961–1990 recommended by WMO (WMO, 2017) used for co...

This paper presents the results of a study on fluctuations in water level Curonian Lagoon (in Baltic Sea). To date, genesis this inland bay as part complex postglacial development southeastern is poorly understood. The data from lithological, geochronological, and phytolith analyses, well assessments plant animal macroremains lagoonal sediments, provide reconstruction local coastal biocenoses d...
