A novel seasonal three-dimensional high-resolution hydrographic gridded data set for the northern Antarctic Peninsula (NAP) based on measurements obtained from 1990–2019 by the ship-based Argo profilers and tagged marine mammals is presented. The main oceanographic features of the NAP are well represented, with the final product having many advantages compared to low-resolution climatologies. In addition, new information on the regional water mass pathways and their characteristics is unveiled.

In this work, we have studied the behaviour of El Niño events in the mid-Pliocene, a period of around 3 million years ago, using a collection of 17 climate models. It is an interesting period to study, as it saw similar atmospheric carbon dioxide levels to the present day. We find that the El Niño events were less strong in the mid-Pliocene simulations, when compared to pre-industrial climate. Our results could help to interpret El Niño behaviour in future climate projections.

Year-to-year changes in rainfall over Africa and South America are influenced by variations in the temperatures of tropical Atlantic variability. Here we investigate how these variations behave under climate change using a series of multi-model experiments. We look at how cold and warm climates of the past relate to future shifts in variability.

In ocean models, Antarctic Bottom Water (AABW) formation is frequently misrepresented. Hence, assessing the causes of spurious formation is important to ensure accurate future simulations. Only one of the state-of-art reanalyses investigated showed AABW formation accurately. Spurious formation in the other two products resulted from opening of open ocean polynyas. The relatively accurate AABW formation in one of the products is an important advance in the simulation of deep ocean circulation.

We present spatially gridded, time-composite mapped data of temperature and salinity of the upper 2000m of the Weddell Gyre through the objective mapping of Argo float data. This was realized on fixed-pressure surfaces ranging from 50 to 2000 dbar. Pressure, temperature and salinity are also available at the level of the sub-surface temperature maximum, which represents the core of Warm Deep Water, the primary heat source of the Weddell Gyre. A detailed description of the methods is provided.

Oceanic eddies are closed circulation features that transport water between regions, taking part in the ocean's heat and salt balance. We perform a comparative eddy census in the East Australian, Agulhas and Brazil currents. We find that eddy propagation in all systems is steered by the local mean flow and bathymetry. Also, eddies present a geographic segregation according to size. Investigating eddy propagation helps us to better understand their effect in local mixing.

We analyzed the ability of the ECCO2 reanalysis to represent the hydrographic properties and variability of Antarctic Bottom Water in the Southern Ocean. After 2004, the opening of an oceanic polynya in the Weddell Sea sector and consequent intense dense water production leads to an unrealistic scenario. Even before 2004, bottom waters are warmer and less dense than expected, while the absolute volume transport and velocity estimates are underrepresented.
