PHOCIS workshop 25 – 29 August 2025
Pelagic High Seas Ocean Ecoregionalisation of the Indian Subantarctic (PHOCIS) will be holding a workshop in Cape Town, South Africa, 25 – 29 August 2025. The main objectives for the Cape Town workshop will be for participants to present and discuss progress on all PHOCIS work packages, but in particular to advance WP4 on Integrated Ocean Management (this study), and WP5 on Research and Monitoring.
The PHOCIS project, “Pelagic High Seas Ocean Ecoregionalisation of the Indian Subantarctic,” is
a scientific initiative focused on dividing the open ocean waters around the Indian subantarctic
region into distinct ecological zones based on their unique marine life and environmental
conditions, with the primary goal of identifying and protecting critical conservation areas within
the subantarctic high seas. The integrated ocean management process will encompass the high
seas within 20°E to 150°E and from 40°S to 60°S. Most of the western area falls within the
CCAMLR boundary whereas the eastern area is outside the CCAMLR boundary.
The main objectives for the Cape Town workshop will be for participants to present and discuss
progress on all PHOCIS work packages, but in particular to advance WP4 on Integrated Ocean
Management, and WP5 on Research and Monitoring. Reports generated will be presented to
CCAMLR via the Scientific Committee and its Working Groups.
PHOCIS is structured into 6 WPs (Work Packages), which are further subdivided into sub-WPs:
WP1 Pelagic ecoregionalisation
WP1.1 Geography
WP1.2 Pelagic oceanographic regions
WP1.3 Plankton and pelagic fish spatial distributions
WP1.4 Seabird and marine mammal distributions
WP1.5 Pelagic ecoregionalisation synthesis
WP2 Connectivity between ecoregions
WP3 Historical and forecasting trends
WP4 Integrated Ocean Management
WP4.1 List of conservation objectives
WP4.2 Human impacts
WP4.3 Systematic Conservation Planning
WP4.4 Legal framework
WP5 Research and Monitoring
WP6 Education and knowledge dissemination
Since its inception meeting in 2019 in Cape Town, PHOCIS has been holding workshops on an
annual basis, either online, in-person, or hybrid.

Every year on 11 August, 
MPA Day, shines a spotlight on the importance of Marine Protected Areas in ocean conservation, sustainable development, and the well-being of communities across the globe. The date—1 August—honours the momentous 2019 declaration of 20 new or expanded MPAs in South Africa. Since then, MPA Day has grown into a United Nations Ocean Decade-endorsed international movement.
The Prince Edward Islands MPA: South Africa’s Sub-Antarctic Treasure: In the remote reaches of the Southern Ocean lies one of South Africa’s most unique and ecologically valuable MPAs—the Prince Edward Islands Marine Protected Area, comprising the volcanic Marion Island and the smaller Prince Edward Island. Together, they represent South Africa’s only sub-Antarctic territory, rich in biodiversity and scientific significance. Declared in 2013, this MPA protects 30% of South Africa’s Southern Ocean territory, encompassing 80% of its marine ecosystem diversity. These waters are a haven for marine life—from krill and Patagonian toothfish to charismatic top predators like seals, seabirds, and killer whales.
South Africa’s pioneering floating university, SEAmester – Class Afloat, is preparing for its eighth voyage aboard the S.A. Agulhas II, setting sail from Cape Town on 17 June 2025 and returning on 27 June 2025. This unique and dynamic marine science programme continues to connect theoretical classroom learning with applied research, all within the working environment of a world-class research vessel.
The voyage is led by Principal Investigator Prof Isabelle Ansorge (left) from the University of Cape Town, whose leadership has been instrumental in shaping SEAmester into one of the most impactful marine science initiatives in South Africa. The logistical and academic coordination of the voyage is managed by Tahlia Henry, whose dedication ensures a seamless blend of teaching, research, and exploration at sea.
The Southern Ocean: A Climate Regulator: The Southern Ocean surrounding Antarctica is a house of climate regulation, absorbing vast amounts of atmospheric carbon and heat. SANAP researchers are actively researching ocean currents, sea ice dynamics, and carbon cycling to better understand how these processes are evolving in a warming world. (Photo credit: A Zietsman)
Protecting Life on the Edge: From the wandering albatross on Marion Island to microscopic extremophiles in Antarctic soils, life persists against all odds in these regions. SANAP’s biodiversity monitoring projects are uncovering the intricate web of life that depends on these environments — and how threats such as invasive species, plastic pollution, and climate variability are impacting these ecosystems.

Long-Term Science, Global Impact: With decades of data collection and continuous human presence at SANAP’s research stations, SANAP long-term research projects offer insights into environmental change. Through collaborations with international partners, SANAP helps shape global understanding of polar processes and their far-reaching effects. This World Environment Day, SANAP celebrates the resilience of our southernmost ecosystems and the SANAP community is dedicated to its preservation. As stewards of the Antarctic and sub-Antarctic, SANAP remain committed to advancing knowledge, promoting conservation, and ensuring these unique environments endure for future generations.

Every year on April 25th, we celebrate International Penguin Day—a global reminder of the unique role penguins plays in our planet’s ecosystems. These birds are not just symbols of the icy South—they are indicators of ocean health and climate change. From the sub-Antarctic islands to the Antarctic continent itself, penguins serve as sentinels of the sea, helping scientists track environmental shifts that affect us all.
South Africa plays a vital role in this mission through its National Antarctic Programme (SANAP), which supports long-term ecological research at key sites such as Gough Island, Marion Island, and Antarctica. These research stations are crucial hubs for studying penguin populations like the Northern Rockhopper on Gough Island and the Macaroni penguins on Marion Island. Scientists monitor breeding patterns, foraging behaviour, and survival rates—data that provide early warnings about oceanic changes. In Antarctica, SANAP researchers study Adélie and Emperor penguins, whose survival is intimately tied to the health of sea ice and krill populations.
By investing in these research efforts, South Africa not only contributes to global conservation science but also highlights the importance of protecting our shared polar heritage. This International Penguin Day let’s celebrate the science that keeps these beloved birds waddling into the future.
