This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace metals, in particular iron (Fe), serve as essential nutrients for phytoplankton, which are at the base of almost all food webs in the ocean and are an important regulator of CO2February 1, 2023). in Earth’s atmosphere. Thus, understanding the mechanisms by which the oceans are supplied with iron and other trace metals is of critical importance to identifying potential changes to trace metal fluxes in the future and improving our estimates of primary productivity. Margins (both continental and ocean/volcanic) can serve as important sources for trace metal delivery to the ocean. Here, we investigate Al, Mn, and Fe cycling in the Solomon Sea, the Gulf of Alaska, and the Mariana Back Arc to better understand the importance of margin input on open ocean chemistry. In the Solomon Sea, water flows past many land masses via strong currents and feeds the Equatorial Undercurrent, which upwells in the high nitrate low chlorophyll eastern equatorial Pacific Ocean. The EUC has a core of elevated trace metals, and so improving our understanding where these enrichments come from will help us better understand the global carbon cycle. In the Solomon Sea, we observe local enrichments of Al and Mn at stations within the basin, however a mass balance suggests that inflowing water is already enriched in trace metals, and the outflowing water has a similar net trace metal composition as the inflowing water. Ultimately, inputs of Al and Mn are short-lived and do not persist through the basin. The coastal Gulf of Alaska is an important source of trace metals to the iron-limited central Gulf of Alaska. Because climate change is likely impacting the hydrodynamics in this region, better understanding the seasonality of fluxes of Al and Mn will help constrain global metal budgets and improve models. Sampling in this region has been primarily focused during the summer months, when river runoff is high, and leaves gaps in our understanding of wintertime processes. We observed a strong seasonal cycle, where cycling of trace metals is driven by sediment resuspension and vertical mixing during the winter and spring and by glacial meltwater inputs during the summer. Despite the high inputs via rivers and sediment, concentrations are relatively low past the shelf break. In the Mariana Back arc, the shallow volcanos of the Mariana Arc could enrich surface waters in Fe and Mn via hydrothermal vents or sediment resuspension processes. To understand whether the Mariana arc volcanoes contribute significantly to the surface ocean Fe pool where primary productivity may be enhanced by addition of Fe, we sampled surface water (

Available in PDF, EPUB and Kindle. Book excerpt: Elements of Physical Oceanography is a derivative of the Encyclopedia of Ocean Sciences, 2nd Edition and serves as an important reference on current physical oceanography knowledge and expertise in one convenient and accessible source. Its selection of articles—all written by experts in their field—focuses on ocean physics, air-sea transfers, waves, mixing, ice, and the processes of transfer of properties such as heat, salinity, momentum and dissolved gases, within and into the ocean. Elements of Physical Oceanography serves as an ideal reference for topical research. References related articles in physical oceanography to facilitate further research Richly illustrated with figures and tables that aid in understanding key concepts Includes an introductory overview and then explores each topic in detail, making it useful to experts and graduate-level researchers Topical arrangement makes it the perfect desk reference

Available in PDF, EPUB and Kindle. Book excerpt: The oceans and atmosphere interact through various processes, including the transfer of momentum, heat, gases and particles. In this book leading international experts come together to provide a state-of-the-art account of these exchanges and their role in the Earth-system, with particular focus on gases and particles. Chapters in the book cover: i) the ocean-atmosphere exchange of short-lived trace gases; ii) mechanisms and models of interfacial exchange (including transfer velocity parameterisations); iii) ocean-atmosphere exchange of the greenhouse gases carbon dioxide, methane and nitrous oxide; iv) ocean atmosphere exchange of particles and v) current and future data collection and synthesis efforts. The scope of the book extends to the biogeochemical responses to emitted / deposited material and interactions and feedbacks in the wider Earth-system context. This work constitutes a highly detailed synthesis and reference; of interest to higher-level university students (Masters, PhD) and researchers in ocean-atmosphere interactions and related fields (Earth-system science, marine / atmospheric biogeochemistry / climate). Production of this book was supported and funded by the EU COST Action 735 and coordinated by the International SOLAS (Surface Ocean- Lower Atmosphere Study) project office.

Available in PDF, EPUB and Kindle. Book excerpt: Oceans account for 50% of the anthropogenic CO2 released into the atmosphere. During the past 15 years an international programme, the Joint Global Ocean Flux Study (JGOFS), has been studying the ocean carbon cycle to quantify and model the biological and physical processes whereby CO2 is pumped from the ocean's surface to the depths of the ocean, where it can remain for hundreds of years. This project is one of the largest multi-disciplinary studies of the oceans ever carried out and this book synthesises the results. It covers all aspects of the topic ranging from air-sea exchange with CO2, the role of physical mixing, the uptake of CO2 by marine algae, the fluxes of carbon and nitrogen through the marine food chain to the subsequent export of carbon to the depths of the ocean. Special emphasis is laid on predicting future climatic change.

This book was released on 2012-12-06 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book arises from a NATO-sponsored Advanced Study Institute on 'The Role of Air-Sea Exchange in Geochemical Cycling' held at Bombann@§. near Bordeaux, France. from 16 to 27 September 1985. The chapters of the book are the written versions of the lectures given at the Institute. The aim of the book is to give a comprehensive up-to-date coverage of the subject. presented in a teaching mode. The chapters contain much recent research material and attempt to give the reader an understanding of how the role of air-sea exchange in geochemical cycling can be quantitatively assessed. In the last decade, major advances in the fields of marine and atmospheric chemistry have underlined the role of physical, chemical and biological processes at and near the air-sea interface in a number of geochemical cycles (C. S, N, metals etc ... ). Further, there is strong concern over the anthropogenic perturbation of these cycles on both regional and global scales. The first part of the book (Chapters 1 to 8) provides a review of topics fundamental to such studies. These topics include concepts in geochemical modelling, assessment of atmospheric transport from sources to the oceans. description of mixing and transport processes within the ocean for both dissolved and particulate materials, quantification of air-sea fluxes for both gases and particles, photochemical transformations in the atmospheric and oceanic boundary layers.
