Context. Oceanic tides are a major source of tidal dissipation. They drive the evolution of planetary systems and the rotational dynamics of planets. However, two-dimensional (2D) models commonly used for the Earth cannot be applied to extrasolar telluric planets hosting potentially deep oceans because they ignore the three-dimensional (3D) effects related to the ocean’s vertical structure.

Our goal is to investigate, in a consistant way, the importance of the contribution of internal gravity waves in the oceanic tidal response and to propose a modelling that allows one to treat a wide r

Abstract A common term in the continental and oceanic components of the global water cycle is freshwater discharge to the oceans. Many estimates of the annual average global discharge have been made over the past 100 yr with a surprisingly wide range. As more observations have become available and continental-scale land surface model simulations of runoff have improved, these past estimates are cast in a somewhat different light. In this paper, a combination of observations from 839 river gauging stations near the outlets of large river basins is used in combination with simulated runoff field

Abstract A characteristic feature of global warming is the land–sea contrast, with stronger warming over land than over oceans. Recent studies find that this land–sea contrast also exists in equilibrium global change scenarios, and it is caused by differences in the availability of surface moisture over land and oceans. In this study it is illustrated that this land–sea contrast exists also on interannual time scales and that the ocean–land interaction is strongly asymmetric.

Abstract:
This review aims to bring into focus the current understanding of hydrothermal systems and plume dynamics, tracers of hydrothermalism and the contribution of iron from hydrothermal vents to the global oceanic iron budget. The review then explores hydrothermal effect on surface ocean productivity. It is now well documented that scarcity of iron limits the production of chlorophyll-producing organisms in many regions of the ocean that are high in macronutrients. However, it is only recently that hydrothermal inputs have gained recognition as a source of Fe to the deep oceans that may potentially

Inoperative grammatology of post(g)locality followed by the incremental desires of neoliberal elites to marketize abundant oceanic resources scattered across the world renders the oceans extremely vulnerable—an appalling phenomenon which at once lays bare the vulnerability of the oceans conditioned by the strands of ‘precariousness’ and at times calls for the actualization of ‘micropolitics of care’—an ethically sound exercise which seems to be able to hold the oceans back from being economically subjected to the predatory ‘faces’ of contemporary neoliberal precarity.

Abstract:
Abstract Several solar system moons harbor subsurface water oceans; extreme internal heating or solar irradiation can form magma oceans in terrestrial bodies. Tidal forces drive ocean currents, producing tidal heating that affects the thermal−orbital evolution of these worlds. If the outermost layers (ocean and overlying shell) are thin, tidal dynamics can be described using thin-shell theory. Previous work assumed that the ocean and shell's thickness and density are uniform. We present a formulation of thin-shell dynamics that relaxes these assumptions and apply it to several cases of interes

Abstract. Virioplankton are a key component of the marine biosphere in maintaining diversity of microorganisms and stabilizing ecosystems. They also contribute greatly to nutrient cycles/cycling by releasing organic matter after lysis of hosts. In this study, we constructed the first global viral oceanography database (gVOD) by collecting 10 931 viral abundance (VA) data and 727 viral production (VP) data, along with host and relevant oceanographic parameters when available. Most VA data were obtained in the North Atlantic (32 %) and North Pacific (29 %) oceans, while the southeast Pacific and

This article examined the ethical and moral dimensions of Illegal, Unreported and Unregulated fishing and related crimes and explores the means to realize justice for the oceans. It needed a new paradigm for addressing the issues. The methods of discussion used statute approach and philosophical approach. Based on the research, it was known that IUU fishing related to other crimes and Transnational Organized Crime, so it was necessary to recognize the concept of transnational organized fisheries crime. The IPOA-IUU fishing and UNCLOS 1982 were not adequate to counter it. In the terms of ethics

Abstract A society is known as low carbon society where individuals cut down the amount of carbon dioxide (CO2) emissions generated from different human activities without affecting any development needs. The increasing presence of carbon emissions has increased the need for urgent actions in this regard. To mitigate the effect of climate change ocean’s contribution is remarkable. But humans are treating oceans to dispose of their waste, which is affecting the ocean’s capacity of carbon sequestration.

The pressing environmental crises of the Anthropocene are inherently connected to ocean health. Yet, the oceans are currently in a critical state. The article explores the idea of giving rights to oceans as one way to enhance their legal protection. It draws on scholarship and practice regarding the existing legal rights of nature, and discusses the challenges and prospects of ocean rights. In doing so, the article raises and addresses three fundamental questions for the recognition of such rights: first, why oceans should hold their own rights in the first place; second, who, i.e. what exact

Drawing on research on the exploration of the ocean, it analyzes the production of popular images of the sea. The entry of humans into the depths of the oceans in the twentieth century did not revitalize myths of mermaids but rather retold oceanic myths in a modern fashion. Three stages stand out in this evolution of diving mobility. In the 1920s and 1930s, scenes of divers walking under water were the dominant motif. From the 1940s to the 1960s, use of autonomous div

Organized precipitation systems, such as mesoscale convective systems (MCSs; precipitation area > 2000 km2), contribute to 88% of the LH above 7 km over tropical land and 95% over tropical oceans. LH over tropical land is mainly from convective precipitation, and has one vertical mode with a peak from 4 to 7 km. There are two vertica

Until recently, most historians shared a prejudice in favour of the history of land, territory and their human inhabitants. Yet two-thirds of the world’s surface is water and much of human history has been conducted on its shores, around its seas and across its oceans. This article proposes reimagining the history of the world through its oceans and seas and examines the multiple genealogies of oceanic history, Mediterranean, Pacific and Atlantic among them. It argues that these models do not exhaust the potential for an oceanic history of the world. It takes the example of the Atlantic and it
