A serious allegation of polluting practices and mistreatment of military personnel has triggered an internal investigation at the Petrel joint Antarctic base, one of the strategic facilities of the Argentine Antarctic system .

The case is being analyzed by the Joint Antarctic Command (COCOANTAR), headed by Rear Admiral Maximiliano Mangiaterra , the body responsible for the logistics and permanent operation of the bases under the Joint Chiefs of Staff.

The formal presentation was made by the second in command of the Petrel base, Lieutenant Commander Amílcar Acosta , through a memorandum dated January 10, in which the irregularities are attributed to the head of the installation, Marine Corps frigate captain Cristian Gabriel De Gregori.

The document cites “repeated breaches of current environmental regulations” and “systematic mistreatment” of crew members during the 2025 Antarctic Campaign.

The most serious issue is related to the environmental impact. According to the report submitted to the authorities, direct verbal orders were allegedly given to dispose of remaining fuels—JP1 for aircraft, gasoline, diesel—and lubricating oils by dumping and burning them in a metal container.

These practices would have generated a critical risk of contamination of the Antarctic soil, fauna and biodiversity, in alleged violation of the Protocol to the Antarctic Treaty on Environmental Protection, which prohibits open burning and establishes a strict waste management system.

The complaint also includes the uncontrolled incineration of solid waste, including expired food, plastics, rubber, and construction materials.

On the Antarctic continent, only certain organic waste can be treated locally and only using special equipment that filters emissions, while hazardous waste must be removed from the territory for final disposal on the continent.

The context exacerbates the situation: Petrel Base is currently undergoing a complete recovery and expansion, with construction underway to transform it into a key hub for air and naval operations deep into Antarctica. If the irregularities are confirmed, Argentina could face international scrutiny within the Antarctic system.

In parallel, the memorandum describes a deteriorating climate of coexistence, with accusations of the use of hostile language, intimidation and verbal humiliation towards subordinates, including the base doctor.

Experts consulted warn that extreme isolation and living in confined spaces exacerbate conflicts when leadership skills fail.

The investigation is expected to determine responsibilities, clarify whether there was incompetence in the management of the base or a sustained internal conflict, and establish any disciplinary sanctions.
