Contrasting Discrepancy in the Sea Level Budget Between the North and South Atlantic Ocean Since 2016

Earth and Space Science
The discrepancy in the observed global mean sea level budget increased significantly since 2016, but the budget discrepancy over basin‐scales is unclear.

Skilful Seasonal Prediction of Ocean Surface Waves in the Atlantic Ocean

Geophysical Research Letters, 2019
Ocean surface wave height in the Atlantic Ocean is strongly influenced by the North Atlantic Oscillation (NAO). Here we demonstrate for the first time a skilful seasonal forecast for wave height in the Atlantic Ocean, produced by a seasonal prediction ...

Global modeling study of potentially bioavailable iron input from shipboard aerosol sources to the ocean [PDF]

, 2013
Iron (Fe) is an essential element for phytoplankton. The majority of iron is transported from arid and semiarid regions to the open ocean, but it is mainly in an insoluble form.

Dental crown morphological variation and heterodonty in carcharhiniform sharks

The Anatomical Record, EarlyView.
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

Revisiting the multidecadal variability of North Atlantic Ocean circulation and climate

Frontiers in Marine Science
The World Ocean’s surface, particularly in the North Atlantic, has been heating up for decades. There was concern that the thermohaline circulation and essential climate variables, such as the temperature and salinity of seawater, could undergo ...

Decadal predictions of the cooling and freshening of the North Atlantic in the 1960s and the role of ocean circulation [PDF]

, 2014
In the 1960s North Atlantic sea surface temperatures (SST) cooled rapidly. The magnitude of the cooling was largest in the North Atlantic subpolar gyre (SPG), and was coincident with a rapid freshening of the SPG.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

The Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Atlantic origin of the arctic biota? Evidence from phylogenetic and biogeographical analysis of the cheilostome bryozoan genus pseudoflustra. [PDF]

PLoS ONE, 2013
The intricate geological evolution of the Arctic Ocean is paralleled by complexities in the biogeographical and phylogenetical histories of the Arctic biota, including bryozoans. Here we present revised taxonomic descriptions for all known species of the

The musculature and skeleton of the pelvic fin of the crocodile shark, Pseudocarcharias kamoharai (Matsubara, 1936) (Elasmobranchii: Lamniformes): Morphology and sexual dimorphism

The Anatomical Record, EarlyView.
This work brings new information on the sexual characteristics of the crocodile shark (Pseudocarcharias kamoharai) exploring the pelvic fin musculature, as well as the siphon sac and the musculature and skeleton of the clasper. Our paper is the first to point out clearly the sexual dimorphism related exclusively to the pelvic fin musculature in males ...

An Ocean Memory Perspective: Disentangling Atmospheric Control of Decadal Variability in the North Atlantic Ocean

Geophysical Research Letters
An ocean memory framework is proposed to reveal the atmosphere's influence on ocean temperatures. Anomalous atmospheric forcing alters the ocean state through two mechanisms: short‐term, local effects involving air−sea heat fluxes and Ekman circulation ...
