“…There is increasing focus being given to the changes to the biota in the Antarctic region, either through the introduction of species directly by human-mediated vectors (vessel traffic, ballast water) or through the effects of changing climate on algal seasonality, depth distributions and habitat changes and potentially influencing competitive relationships between resident species, as well as range expansions and the survival of sub-Antarctic or cold temperate species, with consequences for the native Antarctic biota (e.g. Mystikou et al 2014, Chown et al 2015, Schoenrock et al 2016, Valdivia 2020. Improved baseline information about the macroalgal flora is needed to fully understand changes over time.…”

The macroalgae of the Balleny Islands (66°15′S–67°35′S and 162°30′E–165°00′E) have been infrequently collected and the flora remains poorly known. This chain of islands is located on the edge of the Antarctic Circle in the northern Ross Sea, ~250 km north of the coast of northern Victoria Land, and it represents the most northerly land in the Ross Sea region. As well as being very remote, access to these islands is difficult given the highly variable prevailing ice conditions. We summarize the macroalgal floras of the Balleny Islands and the Ross Sea, including reporting new records, extending the known distribution of other taxa and highlighting the need for further taxonomic research on some of the most common and widespread species. Many of the taxa reported have been collected on few occasions and, as a consequence, there is insufficient material available, including reproductively mature samples, for some species to be fully documented. While these collections are providing intriguing insights into the relationships between the macroalgae found around the Antarctic continent, the full biodiversity of the Balleny Islands remains to be investigated, and further collections are required to enable detailed comparisons with other parts of the Antarctic region.
