Azwianewi (Newi) Makhado (Oceans and Coasts, Department of Forestry, Fisheries and the open access journal CCAMLR Science on seabird assemblages, abundance, and distribution in the African Sector of the southern Indian Ocean.

The paper’s abstract follows:

“Seabird distributions in the Southern Ocean are influenced by the location and accessibility of suitable breeding sites, but also by the environmental factors that influence the distribution and availability of their prey.  For example, oceanic fronts, concentrate prey at their surface and therefore present important foraging areas for many seabirds.  This study investigated the latitudinal distribution and abundance of seabirds in the African sector of the Southern Ocean.  In particular, we investigated the relationship of seabird assemblages and densities to key biophysical environmental parameters (SST, sea surface height, bathymetry) and the main oceanic fronts.  There was a high density of seabirds north of the Subtropical Convergence (STC), which is situated at approximately 39°S, with declining densities farther south.  There was latitudinal segregation between several species, e.g. black-browed albatross (Thalassarche melanophris) occurred north of the STC, and grey-headed albatross (T. chrysostoma) occurred to south of it.  The Subantarctic Front (SAF) and the Antarctic Polar Front (APF) had less influence on seabird populations than the STC.  Latitude was the greatest predictor of seabird assemblages and densities, reflecting environmental gradients in physical and biological parameters and their influences on prey distributions.  Of the environmental parameters, sea surface temperature and bathymetry were the most important physical features influencing seabird assemblages.  In particular, the density of seabirds north of STC declined with increasing sea surface temperature and had a negative relationship with bathymetry, with most seabirds occurring in shallower waters.  In contrast, seabird density had a positive linear relationship with sea surface height.  Relationships with other environmental parameters, such as wind, salinity and chlorophyll concentration (as a proxy for productivity), were less well-defined.”

At-sea observation and tracking data sets reviewed for seabirds in the southern Indian Ocean

Ryan Reisinger (School of Ocean and Earth Science, University of Southampton, United Kingdom) and colleagues have published in the open access journal CCAMLR Science on data sources for seabird and marine mammal distribution in the southern Indian Ocean.

The paper’s abstract follows:

“Numerous seabird and marine mammal species occur, often in high abundance, in the subtropical and subantarctic zones of the southern Indian Ocean.  They breed, moult and rest at French, South African and Australian islands in the region and forage at sea in areas including the Exclusive Economic Zones of these nations, Areas Beyond National Jurisdiction and also the area to which the Convention on the Conservation of Antarctic Marine Living Resources applies.  Information on the at-sea distribution of these species is important for understanding ecosystem patterns and processes in the region, and is a key component of any spatial conservation and management frameworks.  Information on the distribution of marine predators is widely used to define priority areas for conservation and management, with several such initiatives already having been implemented in the extended Southern Ocean.  Seabird and marine mammal distribution has been studied mainly using two methods: animal-borne biotelemetry/biologging and at-sea sighting records.  Here, we give an overview of data on the distribution of marine mammals and seabirds – collected mainly through long-term tracking programmes at French and South African islands – with the aim of identifying data sources that can inform pelagic ecoregionalisation to support spatial conservation and management planning in this region.  We identify priorities for further distribution data collection related to life-history stages, sites and species and we identify broader challenges for understanding marine predator distribution in this region, towards spatial conservation and management planning.”

Visit New Zealand’s sub-Antarctic islands: True Young Explorer Scholarships open for the 2025/26 Season


The megaherb Campbell Island Daisy

Applications are now open for 2025/26 True Young Explorer Scholarships with new Zealan-based Heritage Expeditions.  The scholarships represent a reduction in the listed cost to travel to New Zealand and Australia's sub-Antarctic Islands as well as the remote Ross Sea Region of Antarctica.  Holders of scholarships are expected to contribute 30% of the advertised cost of the expedition, payable on confirmation of the scholarship berth.

“Every year Heritage Expeditions takes small groups of intrepid travellers on voyages to some of the world’s most unique and remote islands, coasts and shorelines aboard our purpose-built expedition ships.  Founded in 1984 by the Russ family in Christchurch, New Zealand, we are still proudly family-owned and operated contributing to conservation through experiential learning, providing funds for research and management, and our ongoing legacy of creating ‘ambassadors’ through our True Young Explorer Scholarships.

True Young Explorer Scholarships provide a limited number of younger people (aged 18 - 30 years) with the opportunity to join expeditions to experience our remarkable Subantarctic Islands at a fraction of what it would otherwise cost.  In doing so, our aim is to create a league of ‘ambassadors' inspired to help raise the profile and protect these precious areas, and the unique flora and fauna inhabiting them, for future generations.

To secure a scholarship, we are looking for individuals who are as passionate as we are about giving a voice to, and protecting, New Zealand and Australia's Subantarctic Islands and the Southern Ocean.  Whether you are studying science, an artist, in media, involved in community organisations, a teacher or ... we want to know how you will share your experience travelling aboard our expeditions on Heritage Adventurer alongside likeminded passengers and an incredibly experienced expedition team of naturalists, biologists and historians on the voyage of a lifetime.”

Read more here, including how to apply.  Applications close on 22 September 2025.

First survey of Heard Island in 20 years to take place this coming austral summer

During the 2025/26 austral summer, the Australian Antarctic Program will undertake two voyages to Heard Island and McDonald Islands (HIMI) using Australia's icebreaker, RSV Nuyina equipped with two helicopters and temporary field huts.  It will be first research visit to Heard Island in more than 20 years.  Surveys of breeding seabirds will include the ACAP-listed Black-browed Albatross Thalassarche melanophris and Southern Giant Petrel Macronectes giganteus.

“High pathogenicity avian influenza (HPAI) has not yet reached Australia, Australian Antarctic Territory nor - to anyone's knowledge - either of Australia’s two sub-Antarctic island groups, Macquarie Island or HIMI.  However, affected animals have been found on the French Kerguelen and Crozet sub-Antarctic islands, which are only 450 km from HIMI.  Wildlife ecologist Dr Julie McInnes and her team are heading to Heard Island to survey seabird populations, map breeding colonies, and monitor signs of bird flu, working in collaboration with the seal survey team.”

Strict protocols will be in place to safeguard the environment, and all activities will be implemented in accordance with environmental permits.

1st Place: Ian Gonzalez

Design entries had to be contestants' original, hand-drawn creations and not be traced or copied from photographs or other artists' works.  No photography or Artificial Intelligence (AI) computer-generated art was accepted.  Judging was on the basis of design, depiction of native species within the lands and waters of Midway Atoll, if wildlife are portrayed, artistic composition, and suitability for reproduction on merchandise.

A total of 31 artworks was submitted,  judged by FOMA President Wayne Sentman, FOMA Vice President Helen Dunlap, FOMA volunteer Keelee Martin, Hawaiian artist and author Patrick Ching and Assistant Professor of Hawaiian language J. Hauʻoli Lorenzo-Elarco  Additionally, followers of the Friends Facebook group could vote for their favourite from 10 short listed artworks in a “People’s Choice Award".
