🇬🇧 English

NOAA has issued three letters of authorization allowing TGS to incidentally disturb marine mammals during geophysical survey work tied to oil and gas activity in the Gulf of America. The authorizations do not allow intentional harm, but they permit limited incidental take under Marine Mammal Protection Act rules. TGS and its survey contractors must follow mitigation, monitoring, and reporting requirements. The notice matters mainly for offshore oil and gas survey operators, environmental compliance teams, and marine conservation stakeholders tracking permitted activity in the Gulf.
