A holistic review is given of the Southern Ocean dynamic system, in the context of the crucial role it plays in the global climate and the profound changes it is experiencing. The review focuses on connections between different components of the Southern Ocean dynamic system, drawing together contemporary perspectives from different research communities, with the objective of closing loops in our understanding of the complex network of feedbacks in the overall system. The review is targeted at researchers in Southern Ocean physical science with the ambition of broadening their knowledge beyond their specific field, and aims at facilitating better‐informed interdisciplinary collaborations. For the purposes of this review, the Southern Ocean dynamic system is divided into four main components: large‐scale circulation; cryosphere; turbulence; and gravity waves. Overviews are given of the key dynamical phenomena for each component, before describing the linkages between the components. The reviews are complemented by an overview of observed Southern Ocean trends and future climate projections. Priority research areas are identified to close remaining loops in our understanding of the Southern Ocean system. Plain Language Summary: The United Nations has identified 2021–2030 as the Decade of Ocean Science, with a goal to improve predictions of ocean and climate change. Improved understanding of the Southern Ocean is crucial to this effort, as it is the central hub of the global ocean. The Southern Ocean is the formation site for much of the dense water that fills the deep ocean, sequesters the majority of anthropogenic heat and carbon, and controls the flux of heat to Antarctica. The large‐scale circulation of the Southern Ocean is strongly influenced by interactions with sea ice and ice shelves, and is mediated by smaller scale processes, including eddies, waves, and mixing. The complex interplay between these dynamic processes remains poorly understood, limiting our ability to understand, model and predict changes to the Southern Ocean, global climate and sea level. This article provides a holistic review of Southern Ocean processes, connecting the smallest scales of ocean mixing to the global circulation and climate. It seeks to develop a common language and knowledge‐base across the Southern Ocean physical science community to facilitate knowledge‐sharing and collaboration, with the aim of closing loops on our understanding of one of the world's most dynamic regions. Key Points: Contemporary perspectives are reviewed on the different components of the Southern Ocean dynamic system from distinct research communitiesKey connections between different components of Southern Ocean dynamics are highlightedCross‐cutting priorities for future Southern Ocean physical science are identified [ABSTRACT FROM AUTHOR]

While numerous studies have explored prevalence and determinants of intimate partner violence (IPV), one area that has yet to be sufficiently explored is whether men and women agree on the acts, behaviours, and attitudes that comprise IPV. Through the use of concept mapping, we examined the similarities and differences in the conceptualization of IPV among a diverse sample of men and women. Although men and women conceptualized physical and sexual violence similarly, men tended to rate non-physical behaviors related to control as less important to the definition of IPV than women. Moreover, even when men and women used similar labeling language for grouping of items, the statements included in each cluster were substantially different for non-physically abusive items. A greater understanding of similarities and differences in the conceptualization of IPV by gender can help inform appropriate gender specific IPV intervention and prevention efforts., Author(s): Patricia O'Campo [sup.1] , Yu Janice Zhang [sup.1] , Mairi Omand [sup.2] , Alisa Velonis [sup.3] , Michael Yonas [sup.4] , A.

The Southern Ocean plays a vital role in global ocean circulation, and the Polar Front (PF) is one of its most important physical features. The PF meander south of Tasmania, around 153°E, 55°S, is a very dynamic region which spawns mesoscale eddies, and influences local biogeochemistry and sea-air interaction. By using voyage and ancillary data, we investigated the unusually strong spring bloom in the vicinity of the PF meander in 2018. We infer that the upwelling of deep water at the front and in eddies, brings macronutrients and dissolved iron (dFe) to the surface. Chlorophyll concentration peaked at over 0.6 mg m-3, which is anomalously high for this area. With reduced iron limitation, the physiological characteristics of phytoplankton in the northern, downstream part of the study area also changed. The photochemical efficiency was improved and released this area from its usual high-nutrient low-chlorophyll (HNLC) status. This was mainly indicated by the increase in the dawn Fv/Fm maximum (indictor of photochemical efficiency) from 0.2 to over 0.5. With the biomass increase and healthier community status, we observed consumption of surface dissolved inorganic carbon and increased particulate organic carbon production to about 40 μmol L-1, forming a weak local carbon sink. Through the investigation of multiple years, a weak positive correlation between mixed layer depth shoaling and phytoplankton growth was found, but there was significant interannual variability in this relationship, likely caused by variable eddy conditions and dFe delivery.

Background: This study aims to explore the conceptualization of intimate partner violence (IPV) among men and women from diverse subpopulations in Toronto, ON, Canada. Relatively few research efforts have been made to examine differences in conceptualizations of IPV across populations of different race and ethnic backgrounds. Methods: Using concept mapping methodology, we sampled 67 women and men identified concepts and groups of concepts (domains) that reflected their understandings of the behaviours and attitudes that comprised IPV. We also determined the relative importance of each concept and domain as a contributor to IPV. Results: ‘External and Cultural Influences’, ‘Victim Response to Abuse’ and ‘Social and Emotional Manipulation’ were a few domains that participants rated as moderately or highly important contributors to IPV. These conceptual domains are often left out of commonly used IPV measures. Conclusions: Our findings have important implications for the conceptualization of IPV and for future IPV measurement and measurement tool development. [ABSTRACT FROM AUTHOR]

Turbulent mixing plays an important role in large-scale oceanic processes such as watermass transformation, global overturning circulation and stratification. The sensitivity of ocean models to the spatial and temporal variability of mixing has implications on ocean heat uptake in climate models and ocean circulation in regional models. Partly because of the lack of observations, the turbulent mixing in the southeast Indian Ocean is not well described. This study investigates the spatial and temporal variability of turbulent mixing in the eastern South Indian Ocean (SIO) using Electromagnetic Autonomous Profiling Explorer (EM-APEX) floats, vertical microstructure profilers, and shipboard CTD data during 2013. The EM-APEX floats sampled the upper ocean with a frequency of 8 profiles per day which is high enough to resolve the internal waves who change the local mixing when they break in the ocean interior. The floats measured current velocities and water mass properties up to a depth of 1200 m with a resolution of 3 - 4 m in the vertical. By applying a shear-strain parameterization on the float data, we estimated the diapycnal diffusivity in the upper 1200 m of the ocean. We observe elevated diffusivity associated with wind near the surface, bathymetry and mesoscale eddies. Both warm core and cold core eddies impact the distribution of turbulent mixing. High mixing observed in the warm core eddy suggests trapping of near-inertial waves. We also observe elevated mixing below cold core eddy associated with deep reaching near-inertial waves. By applying a strain-only parameterization on the shipboard data, we observe elevated diffusivity near bathymetry associated with bottom-generated internal waves. Elevated mixing is observed at depths corresponding to Antarctic Intermediate Water and Subantarctic Mode Water suggesting that turbulent mixing impacts the modification of watermasses in this region. This work improves our understanding of turbulent mixing variability in the eastern SIO, a climatically important region for Australia. [ABSTRACT FROM AUTHOR]
