First: Errors. ^-^
Mark introduces you and you take your place next to the presentation board. You take a deep breathe.
You read the brochure more to see what your offsite weekend will be like. This time of the year, the conditions are right so bioluminescence occurs.
I think you need to include what is being bioluminescent, the reader has some difficulty linking bioluminescent marine bacteria making the water glow, and “bioluminescence occuring”.
As a suggestion:
This time of year the conditions are ideal for bioluminescence to occur in the marine life.
Other than that I’ve enjoyed reading this so far, and look forward to seeing it finished. Keep up the good work.
