Cetacean Stranding Data

 The MMSC is a member of the Greater Atlantic Marine Mammal Stranding Network, so we are on the front lines working together with our fellow network members to help find the answers to marine mammal deaths. We are tasked with being the first responders to facilitate a necropsy to collect any samples that are viable based on the condition of the carcass. Large whale necropsies can take a day or more to complete. The work is grueling and dangerous, requiring a large team of people, each with a specific task, working together as safely and efficiently as possible to complete the examination. When a large whale washes ashore in the Northeast region, oftentimes staff from other stranding organizations will travel in from out of state to assist with the efforts. 

Once stranding organizations such as ourselves have collected the samples, they are then sent to the laboratory pathologists who are responsible for processing and analyzing. When the pathologists have completed their work, the scientists who are tasked with researching the ongoing Unusual Mortality Event (UME) interpret the findings.

It is never recommended for the public to push a stranded animal back into the water. The risk of injury is high, as thrashing dolphins can cause serious injury, and potentially carry zoonotic diseases that can be transferred to humans. Not only is it dangerous for untrained individuals to attempt this, but these animals strand for a reason, and only pushing them back out into the ocean will prolong their suffering and any medical attention they might need. These animals are likely to re-strand in a different location and in a worsened condition. 

The impact of stranding is life-threatening to cetaceans, as they are not anatomically designed to survive on land. Being evolved to live life in the ocean, their body weight and organs are supported by the water around them. When a cetacean is stranded for any length of time, their weight causes damage to their internal organs. Additionally, their skin becomes easily dried out and the animals begin to overheat. They are unlikely to survive even if they are refloated. Euthanasia is often deemed the most humane way to end suffering when the animals are found in poor body conditions due to being stranded.
