    Because of the decrease in sea ice coverage, maritime activities in the polar regions have increased steadily over the years and several issues related to maritime activities have arisen. It is essential to understand these challenges because they could have serious political, environmental, and economic consequences. Although there are significant geographical and legal differences and differences in the types of activities between the Arctic and the Antarctic, a single International Maritime Organization Polar Code covers both regions. In this analysis, changes in polar regions are introduced, and the differences between the Arctic and Antarctic are discussed. The differences in maritime activities in the two polar regions are then discussed, and the Polar Code is evaluated in terms of these differences.

    N2O gas depletes ozone and has a powerful greenhouse effect. Oceans are among the most important N2O sources and have been the subject of extensive studies. Polar oceans are important regions for deep water formation and global-scale thermohaline circulation. Therefore, these water bodies play an important role in the N2O budget, however, these regions were not well studied. This review of previously published studies and data on polar oceans, including both the Arctic Ocean and Southern Ocean, describes the distribution pattern of N2O and possible regulating mechanism of these distribution patterns and shows that the Arctic Ocean and Southern Ocean both represent source and sink regions, suggesting that the source/sink characteristics of the Arctic and Southern oceans and their strengths need further study. Questions related to N2O circulation in polar oceans were proposed, and future work is suggested.

    Identifying home ranges—those areas traversed by individuals in their normal foraging, mating, and parenting activities—is an important aspect of cetacean study. Understanding these ranges facilitates identification of resource use and conservation. Fin and humpback whales occur in Antarctica during the austral summer, but information regarding their home ranges is limited. Using opportunistically collected whale sighting data from eight consecutive summer seasons spanning 2010–2017, we approximate the home ranges of humpback and fin whales around Drake Passage (DRA), West of Antarctic Peninsula (WAP), South Shetland Islands (SSI), an area northwest of the Weddell Sea (WED), and around the South Orkney Islands (SOI). Approximate home ranges are identified using Kernel Density Estimation (KDE). Most fin whales occurred north and northwest of the SOI, which suggests that waters near these islands support concentrations of this species. Most humpback whales were observed around the SSI, but unlike fin whales, their distributions were highly variable in other areas. KDE suggests spatial segregation in areas where both species exist such as SOI, SSI, and WPA. Partial redundancy analysis (pRDA) suggests that the distributions of these species are more affected by spatial variables (latitude, longitude) than by local scale variables such as sea surface temperature and depth. This study presents a visual approximation of the home ranges of fin and humpback whales, and identifies variation in the effects of space and environmental variables on the distributions of these whales at different spatial scales.

    This study was performed to support an expeditionary team of Colombian scientists seeking to promote and undertake research in various scientific fields in Antarctica. The work was part of the Colombian Antarctic program, which comprises various projects intended to lead to a permanent Colombian scientific base being established in the Antarctic. The first step involved installing a Colombian-made wind turbine to produce electricity at a permanent base. The aeolian turbine was designed to provide sufficient electricity to illuminate and heat a small base. The turbine was constructed using readily accessible materials but taking the Madrid Protocol environmental regulations into consideration. The project was performed at the Argentinian Antarctic Marambio Station on Seymour Island, off the Antarctic Peninsula. An initial field study performed in 2015 was the first of three phases of the project. In the initial phase, local meteorological data were gathered to support development of a prototype turbine and to allow a design to be selected that was robust enough for the extreme environmental conditions. The wind turbine was then constructed in Colombia. The second phase involved transporting the turbine to Antarctica and installing it at the Marambio Station in 2018. Finally, the physical conditions of structural and electronic components of the turbine were carefully inspected at the beginning of 2020 (after the turbine had operated continually for ~2 years) to allow repairs to be made and any necessary re-engineering to be performed.

    The article is devoted to the assessment of emissions of air pollutants and greenhouse gases into the atmospheric air in Antarctica from power plants equipped with diesel generator sets, which are the main sources of energy at the Antarctic research stations and the main stationary sources of anthropogenic emissions in the Antarctic. A bottom-up approach to emission inventory for the Antarctic, which allows estimating emissions at various spatial levels by sequentially aggregating emission estimates from point emission sources, has been proposed and applied for the first time. Emissions of CO2, NOx, particulate matter (PM10) and CO by stations, geographical regions, natural domains, biogeographic regions, parts of the continent and the continent as a whole for the modern period were estimated. In the paper yearly emissions are described; the approach allows estimating of emissions of different averaging periods: in addition to yearly emissions, monthly, daily, hourly etc. can be obtained, as well as both averaged and maximum emissions. The estimates obtained can be used to model the transmission and dispersion of pollutants, assess impacts, and develop emission forecasts for various scenarios.

    A number of studies have reported in the last decades the presence of plastics in the Southern Ocean, which are liable to reach the coast and accumulate on the Antarctic Continent. Despite this, there are few data on the amount of plastic pollution on Antarctic beaches below 60°S. Here we provide valuable information about the presence of plastic debris in Byers Peninsula, Livingston Island, South Shetland Islands, an Antarctic Specially Protected Area (ASPA) and a hotspot for biodiversity. A total of 129 locations with between 1 and 5 items were recorded among the 3 survey sites on Byers Peninsula. Most of the observed items are likely to derive from fishing and local sources such as tourism and research activities. We discuss the potential impacts of their presence on local fauna and some of the consequences on the Antarctic ecosystem. From this survey of plastic accumulation in an ASPA, we propose the implementation of mitigation strategies, such as systematic monitoring of the abundance and distribution of plastic waste, in order to identify trends in marine debris and control the levels of plastic pollution in the Maritime Antarctic region.

    Over two dozen global atmospheric chemistry models contributing to the Aerosol Comparisons between Observations and Models (AeroCom) project were used in this study to drive the Los Alamos sea ice model to simulate the black carbon (BC) concentration in melting snow on Arctic sea ice. Measurements of BC during the melting season show concentrations in the range 2.8–41.6 ng·g−1 (average: 15.3 ng·g−1) in the central Arctic Ocean and Canada Basin. Most results from models contributing to the Phase I project were within the 25th and 75th percentiles of the observations, and the multimodel mean was slightly lower than that of the observations. In contrast, there was larger divergence among the Phase II model simulations and the mean value of BC was overestimated. The multimodel mean bias was −3.1 (−11.2 to +6.7) ng·g−1 for Phase I models and +3.9 (−9.5 to +21.3) ng·g−1 for Phase II models. The differences between the models of the two phases were probably attributable to the updated aerosol scheme in the new contributions, in which removal processes are parameterized by considering the actual dimensions and chemical compositions of the particles. This means the removal mechanism acts in a way that is more selective and leads to more BC particles being transported to the Arctic. In addition, higher spatial resolution could be another important reason for overestimation of BC concentration in snow in Phase II models.
