So what does a marine biologist do, exactly?

A typical conversation with someone I just met:

New Person: “So, what do you do?”
Me: “I’m a marine biologist.”
New Person: “That’s so cool! So what do you do exactly?”
That question always stumps me for a moment or two. How does one condense one’s job/career into one sentence? In the end, I usually go with “I go diving and count fish”, which doesn’t really help all that much. After six months of relatively intensive fieldwork, I now have enough visual aids to answer that question with! (Thank you to my awesome teammates for the photos. Whee!)
So, what does a marine biologist do, exactly? In my case, being a marine biologist involves:
Diving and counting fish using fish visual census. We then use the census data to estimate the total fish biomass in the area. We also use the list of fish species found to see if the area is overfished or not. Still learning to identify my fish but I’m getting there. The Philippines has over 1,800 species of marine fish so cut me some slack 😛 Photo by Jem Baldisimo
