Marine environmental response focuses on mitigating the impact of pollution incidents, such as oil spills, chemical discharges, and vessel groundings, to protect marine ecosystems. Rapid response teams deploy containment booms, skimmers, and absorbents to prevent pollutant spread while assessing environmental risks. Advanced technologies, including remotely operated vehicles (ROVs) and dispersants, enhance cleanup efficiency. Collaboration with scientists and regulatory agencies ensures effective remediation and habitat restoration. Prevention measures, such as contingency planning and risk assessments, further reduce future incidents. A well-executed marine environmental response safeguards biodiversity, protects coastal communities, and upholds maritime industry sustainability.
