Showing papers in "Progress in Oceanography in 2018"

TL;DR: In this paper, the authors find that the increase in the Bering Strait throughflow is primarily due to a strong increase in far-0it and mooring data, not changes annual mean flow for the Chukchi Sea (to ∼4.5 months from ∼7.5 weeks).

TL;DR: A synopsis of the current state of the art in the retrieval of core optical properties from satellite ocean color is presented and recommendations for future investment for upcoming missions whose instrument characteristics diverge sufficiently from heritage and existing sensors to warrant reassessing current approaches are made.

TL;DR: In this article, the authors present a short look at the past, a critical analysis of the present capabilities and a foresight of where the field is likely to go and highlight the need for a more complete, spectral, approach in data assimilation.

TL;DR: In this paper, the authors present results from synthetic particle tracking experiments that characterize the interannual and seasonal dynamics of ocean currents and winds likely to influence the transport of Sargassum from the Equatorial Atlantic into the Caribbean Sea.

TL;DR: In this paper, the authors quantify the long-term trends, variability and predictability of marine heatwaves off eastern Tasmania using a high-resolution ocean model for Tasmania's eastern continental shelf.

TL;DR: In this article, the authors used bathymetry data combined with the largest lander-derived imaging dataset that spans the full depth range of three hadal trenches (including adjacent slopes); the Mariana, Kermadec and New Hebrides trenches, the topographic variability, fine-scale habitat heterogeneity and distribution of seabed sediments of these three trenches have been assessed for the first time.

TL;DR: In this paper, the authors present a more refined approach and depict diatom genera that were adapted to more stratified conditions such as those characteristic of the subtropical oligotrophic gyres, and suggest that it is time to abandon oversimplified schemes and recognize the diverse ecology of diatoms.

TL;DR: In this paper, the physical mechanisms of light absorption, scattering, fluorescence and diffraction in microalgae are discussed. And the current optical cell models that describe the absorbance and scattering properties of micro algae are compared and reviewed.

TL;DR: In this article, the mean and breadth of the realized niches based on responses of the group-specific phytoplankton composition to key environmental factors were estimated. And the results showed that variations of major phyto-ankton groups in this system can be explained by different adaptive trade-offs to constraints imposed by temperature, irradiance, and nutrient concentrations.

TL;DR: In this article, the authors synthesize a multidecadal dataset of annual growth of the Arctic endemic kelp Laminaria solidungula and corresponding measurements of in situ benthic irradiance from Stefansson Sound in the central Beaufort Sea.

TL;DR: In this paper, a high-resolution ocean model is used to characterize the local and remote driving mechanisms of the variability of the Patagonian shelf circulation, including the effects of tides, buoyancy fluxes and wind, while remote forcing represents the impact of the adjacent deep-ocean currents.

TL;DR: In this article, the authors examined the variation of Kuroshio subsurface water (KSSW) off the coast of Zhejiang province, China, carried out six monthly cruises from February to July 2015.

TL;DR: In this paper, bottom pressure measurements on the global continental slope of the ocean have been used to monitor the meridional overturning circulation of the oceans, and the results show that boundary pressure variations are coherent over along-slope distances of tens of thousands of kilometres, for several vertical modes.

TL;DR: In this article, full-depth distributions of CDOM absorption coefficients and spectral slopes recorded during the HOTMIX 2014 cruise are presented and their respective environmental drivers resolved, indicating that both water column stability and photobleaching may drive the variability of the UV-A absorbing CDOM components.

TL;DR: In this paper, a model-based long-term Knudsen and TEF analysis of exchange flow in the Western Baltic Sea reproduces the Major Baltic Inflows (MBIs) that have occurred since the 1950s.

TL;DR: In this article, the authors focused on two canyons: (1) the Cassidaigne canyon, located in the eastern part of the Gulf of Lion, and (2) the Bari Canyon System, in the southwestern Adriatic, a site of coral growth that has been hypothesized to respond to hydrographic processes, including the cascading of North Adriaatic Dense Water.

TL;DR: In this article, the spatial distribution and sources of dissolved aliphatic and polycyclic aromatic hydrocarbons (AHs and PAHs), as well as their relationships with a series of biogeochemical parameters (total chlorophyll a, phaeopigment a, suspended particulate matter, particulate and dissolved organic carbon, and nutrients), in surface coastal waters of the Gulf of Gabes (Tunisia, Southern Mediterranean Sea).

TL;DR: In this paper, an unstructured grid hydrodynamic model was applied to a unique domain representing the whole MMBA system, which simulated the tidal propagation and transformation inside each basin and in the straits connecting them.

TL;DR: In this article, the authors compare global differences and similarities in the location and intensity of BNLs measured with two independent instruments over slightly overlapping decadal time periods, and provide a comprehensive comparison of these data sets on a global scale.

TL;DR: In this paper, the authors described the general hydrography in the South Brazil Bight (23-28°S) with emphasis on frontal processes and their role in the structure and functioning of the regional shelf ecosystem.

TL;DR: In this paper, the authors analyzed phytoplankton fluctuations at four automated mooring stations in the North Sea, which measured the response of chlorophyll fluorescence to various environmental variables (tidal and meteorological variables, suspended particulate matter, nitrate and sea surface temperature).

TL;DR: Overall results reported here indicate that the submarine canyons of the Mediterranean Sea can represent hot-spots of abundant and highly diversified fungal assemblages and pave the way for a better understanding of the ecological role of fungi in the largest ecosystem on Earth.

TL;DR: For the first time, the 20-year time series of monthly O2 concentrations at the DYFAMED long-term sampling site in the Ligurian Sea was analyzed in this paper.

TL;DR: In this paper, the authors used a platform at the Ocean Networks Canada NEPTUNE Observatory located in the axis of Barkley Canyon between June 2012 and January 2015 to characterize the megabenthic community and the environmental conditions in the canyon; investigate temporal patterns in the faunal community; and determine the influence of environmental conditions on the observed patterns.

TL;DR: In this paper, the authors used seafloor video imagery combined with acoustic Doppler current and backscatter time-series data from the NEPTUNE observatory to identify the precise timing and seasonal and inter-annual variability in the deep ontogenetic migration of Neocalanus spp. in Barkley Canyon.

TL;DR: In this paper, the local properties of the cold intermediate layer (CIL) in the Black Sea were examined over the period 1960-2015 using a 3D numerical model and realistic forcing.

TL;DR: In this article, a study of 713 age-0 Pacific bluefin tuna (PBF) caught in their nursery waters off the southern coast of Japan and in the East China Sea over an extended study period (1995-2015) was conducted to clarify the spatial and temporal variability of their trans-Pacific migration.

TL;DR: Seasonality of food and grazers and unselective feeding behaviour and the ability to remove highly elongated cells have implications for how copepod feeding is represented in ecological and biogeochemical models.

TL;DR: In this paper, the processes responsible for seasonal migrations, spatio-temporal size-structure, and interannual biomass fluctuations of small pelagic fish were investigated.

TL;DR: In this article, the authors presented an analysis of the mean state of the model FESOM-REcoM2 in a global configuration with an Arctic-wide resolution of 45 km.
