The work
A day, hour by hour

Days swing between boat, lab, and desk — here's a field day for a research biologist:

06:00
Weather check

Read wind and swell forecasts. Go, delay, or scrap today's sampling?

07:00
Load the boat

Pack dive gear, sample bottles, and tags. Run through safety checks.

08:00
Reef survey

Dive transects, counting fish and coral bleaching on waterproof slates.

11:00
Sample collection

Filter water, net plankton, label every vial. One mislabel ruins a sample.

13:30
Lab work

Back on shore, sort plankton under the microscope and freeze tissue for DNA.

15:00
Data crunching

Enter counts, run R scripts. Is that dip real, or noise?

16:30
Mapping habitat

Overlay drone imagery and tag tracks in GIS to see where animals gather.

17:30
Write-up & planning

Draft report notes, then plan next week's sites and timing.

Things you do
  • Head out by boat or dive to survey reefs and track marine animals.
  • Collect water, plankton, and tissue samples and label them carefully.
  • Design studies and decide where, when, and how to sample.
  • Analyze samples under microscopes and with DNA tests in the lab.
  • Crunch survey data with statistics and code in R or Python.
Decisions you’ll make
  • Is the weather safe enough to head out, or should I scrap today's sampling?
  • Is this pattern in my data real, or just noise from too few samples?
  • How sure am I to tell officials this reef needs protection now?
  • Where and when should I sample to get results I can trust?
  • Is this odd result a bad sample, or something new worth chasing?
