Penguin Guano, Climate Data and Argentina’s Role in Antarctica
A study near Argentina’s Marambio Base shows how a local biological process can become relevant for atmospheric chemistry, cloud formation and climate data. The wider issue is Argentina’s ability to turn Antarctic proximity, research stations and South Atlantic logistics into scientific, operational and institutional value.
The insight is simple: Antarctic data depends on infrastructure.
A 2025 study on penguin guano in Antarctica shows how biological activity can become relevant for atmospheric chemistry and climate research. Penguin colonies release ammonia. Together with sulfur compounds from the ocean, this ammonia can support the formation of new aerosol particles that matter for cloud processes and climate models.
For Argentina, the study is relevant because measurements were taken near Marambio, one of the country’s key Antarctic bases. The case shows how research stations, airstrips, logistics, sensors, institutions and South Atlantic gateways turn remote environmental processes into usable data.
Core market reading:
Argentina’s Antarctic role becomes economically relevant when proximity, bases and South Atlantic logistics are translated into climate data, environmental monitoring, research cooperation and operational capability.
The study: guano as a source of climate-relevant particles
The 2025 study “Penguin guano is an important source of climate-relevant aerosol particles in Antarctica” examines how penguin colonies can influence chemical processes in the Antarctic atmosphere.
The mechanism is clear. Penguins produce guano. Guano releases ammonia. This ammonia can react with sulfur compounds that originate from marine biological processes. Under the right conditions, these reactions support the formation of new aerosol particles. Such particles can act as cloud condensation nuclei.
The study also describes the role of dimethylamine. According to the research, dimethylamine can strongly accelerate new particle formation. A local biological process therefore becomes measurable for atmospheric chemistry.
This matters for climate research because clouds remain a difficult and important part of Antarctic climate modelling. Aerosol particles influence how clouds form, how they reflect radiation and how local processes enter larger climate systems.
"The small biological signal matters because it becomes climate data only when it can be measured, maintained and interpreted."
Why Marambio matters
Marambio is one of Argentina’s most important Antarctic bases. It is located on Seymour Island and has an airstrip that allows cargo and passenger flights. That makes it a key logistical point for research, supply and emergency operations.
This infrastructure is essential for scientific work in Antarctica. Instruments need to be installed, operated and maintained. Personnel need safe access. Data needs to be collected, stored and transmitted. Weather, equipment, energy supply and transport determine whether research can continue beyond a short field visit.
The guano study therefore also shows the importance of sites such as Marambio. A penguin colony can create a relevant chemical signal. Usable climate data emerges when that signal is captured by measurement infrastructure and scientific analysis.
Marambio represents a part of Argentina’s Antarctic role that is often less visible than sovereignty debates or political symbolism: operational capability.
Argentina’s Antarctic presence
Argentina is one of the countries with a particularly long Antarctic presence. Orcadas Base has been operated since 1904, and the Argentine Foreign Ministry presents this uninterrupted presence as a central element of national Antarctic policy.
The Instituto Antártico Argentino was founded in 1951. It is one of the country’s central institutions for Antarctic research and forms part of the scientific base of Argentina’s Antarctic policy.
According to official information, Argentina’s Antarctic infrastructure includes six permanent and seven temporary bases. This network supports scientific research, weather and environmental observation, biological studies, geological work, logistics, international cooperation and diplomatic positioning within the Antarctic Treaty System.
Carlini Base is an important example of international cooperation. It hosts the Dallmann Laboratory, operated since 1994 in cooperation with Germany’s Alfred Wegener Institute. This shows how Argentine infrastructure can also function as a platform for international science.
Argentina’s value in Antarctica depends on continuity and capability.
Its presence becomes meaningful when bases, institutions, logistics and international cooperation produce reliable research, data and operational capacity.
From environmental observation to strategic knowledge
The guano study shows a chain that applies to many Antarctic topics.
First, there is a local environmental process: penguins, guano, ammonia and aerosol formation. Then comes measurement: sensors, stations, personnel, samples and data. Scientific interpretation follows: atmospheric chemistry, cloud formation and climate models. The resulting knowledge can then inform environmental policy, fisheries governance, tourism regulation and risk assessment.
This chain is the core of the Antarctic data economy. Value is created by the ability to measure remote environmental processes reliably and translate them into usable knowledge.
For Argentina, geographical proximity to Antarctica is an advantage. The strategic question is whether that proximity can be converted into stable research capacity, logistics and data infrastructure.
Krill, carbon and the economic value of Antarctic data
The importance of Antarctic data is also visible in the case of krill. Antarctic krill is a key species in the Southern Ocean. It feeds penguins, seals, whales, fish and other species. It is also the basis of a commercial fishery.
A 2025 PNAS study estimates the gross annual value of the Antarctic krill fishery at between US$250 million and US$900 million. A separate study on krill carbon sequestration estimates that krill fecal pellets can sequester around 20 million tonnes of carbon per productive season. Depending on the carbon price used, the value of this ecosystem service is estimated at between US$4 billion and US$46 billion.
These figures describe different things. One concerns the fishery. The other concerns an ecosystem service. Together, they show how Antarctic ecosystems increasingly enter economic assessment, fisheries management, climate policy and international regulation.
Reliable data is essential for all of this. Fisheries, protected areas, carbon valuation, tourism and climate risk can only be governed seriously when measurements, monitoring and scientific interpretation are credible.
Why this matters:
In Antarctica, data is not a side product of science. It is a basis for regulation, conservation, fisheries decisions, tourism management and climate-risk assessment.
Ushuaia as an Antarctic access point
Antarctic research does not begin on the ice. It begins in ports, airports, shipyards, warehouses, fuel chains, medical facilities and service networks.
For Argentina, Ushuaia is a central point in this infrastructure. The city is a departure point for cruises, supply operations, vessel movements and logistics services connected to Antarctica.
MercoPress, citing IAATO data, reported 118,491 Antarctic visitors in the 2024/25 season, compared with 122,072 in 2023/24. These figures mainly concern tourism. They still show the operational importance of Antarctic gateway structures: port handling, safety, environmental rules, vessels, personnel, supply and emergency planning.
Ushuaia has also gained political importance. In 2021, an Antarctic logistics pole in Ushuaia was announced with an estimated investment of around US$300 million. In January 2026, El País reported that Argentina’s federal government intervened in the administration of the Port of Ushuaia. The move triggered a dispute with Tierra del Fuego authorities and was also interpreted in geopolitical terms.
For market observers, the operative question is more important than the political noise: can Ushuaia translate its location into reliable port, logistics and service capacity?
"Ushuaia’s Antarctic value depends on ports, services, rules and reliability — not on geography alone."
The legal frame of Antarctic activity
Antarctica is not a normal economic space. The Environmental Protocol to the Antarctic Treaty designates Antarctica as a natural reserve devoted to peace and science. Activities related to mineral resources are prohibited, except for scientific research.
This legal framework changes the economic logic. Antarctica is not a conventional resource frontier. Its economic relevance lies in research, data, logistics, monitoring, tourism management, environmental governance and specialized technical support.
For Argentina, this framework matters. Antarctic relevance is not created through resource extraction. It is created through presence, scientific capability, logistics, international cooperation and credibility within the Antarctic Treaty System.
Where Antarctic science creates demand
Antarctic research and South Atlantic logistics create specialized demand. The required technologies, equipment and services must function under extreme conditions.
This includes sensors, meteorological systems, aerosol measurement, communications infrastructure, laboratory equipment, energy supply, maintenance, cold-weather protection, safety equipment, medical support, waste management, environmental consulting, port services, vessel supply and data infrastructure.
Tourism and fisheries governance create additional needs. High visitor numbers require environmental rules, health protocols, emergency planning and operator reporting. Krill fisheries and protected-area debates increase the need for monitoring, traceability, ecosystem modelling and scientific decision support.
The opportunity for specialized providers is not a broad mass market. It lies in concrete requirements from research institutions, public agencies, logistics operators, port actors, tourism companies and international programs.
- Environmental monitoring: sensors, aerosol measurement, weather data, biodiversity tracking and field instruments.
- Data infrastructure: storage, transmission, modelling, visualization and decision-support systems.
- Logistics and safety: port services, aviation support, emergency planning, medical evacuation and vessel operations.
- Tourism management: visitor management, health protocols, environmental rules and operator reporting systems.
- Fisheries governance: monitoring, traceability, ecosystem modelling and regulatory decision support.
- International research: joint laboratories, polar equipment, scientific instruments and technical services.
What to watch next
The first point to watch is the development of Marambio and Carlini. Operational reliability, research quality, international cooperation and technical modernization will matter more than symbolic statements.
The second point is Ushuaia’s role. Port capacity, regulatory stability, environmental standards and service quality will determine whether the city can use its position as an Antarctic gateway more effectively.
The third point is Antarctic environmental data. As climate risks, fisheries pressure and tourism regulation become more important, credible data will become more valuable.
The fourth point is the krill debate. Fisheries, ecosystem protection and carbon valuation are moving closer together. This makes CCAMLR, the Argentina-Chile proposal for a marine protected area and Southern Ocean monitoring relevant beyond environmental circles.
The fifth point is international research cooperation. The Dallmann Laboratory at Carlini shows how Argentine infrastructure can serve as a platform for international science.
Argentina’s larger Antarctic question
The penguin-guano study is a small entry point into a larger question: what role can Argentina play in the science, logistics and data infrastructure of the South Atlantic?
The country has geographical proximity, long institutional experience, several Antarctic bases, Marambio as an important research and logistics site, and Ushuaia as an access point. Strategic value emerges when these elements are operated reliably, modernized and connected to international cooperation.
Marambio enables measurements in an extremely remote environment. The Instituto Antártico Argentino gives these activities institutional continuity. Ushuaia connects Antarctic activity with South American logistics. International bodies such as CCAMLR and the Antarctic Treaty System turn scientific data into the basis for policy decisions.
Argentina’s opportunity is to play a useful role in South Atlantic research, environmental monitoring, logistics and international governance. The guano study shows this in a small but concrete way: even relevant environmental processes remain invisible without infrastructure.
