Methods & Sampling

2019-04-09:
Coscinodiscus wailesii diatom sinking behavior was recorded after exposure to light conditions or 2, 5, or 7 hours after exposure to dark conditions.
Treatments:
01 Light
02 Dark 2h
03 Dark 5h
04 Dark 7h

2019-04-11:
Coscinodiscus wailesii diatom sinking behavior was recorded after exposure to L1/2 media (replete) or exposure to L1/2 media depleted of one nutrient.
Treatments:
01 Replete
02 N Depleted
03 Si Depleted
04 P Depleted

2019-04-12:
Coscinodiscus wailesii diatom sinking behavior was recorded after exposure to L1/2 media (replete) or L1/2 media depleted of one nutrient or after exposure to L1/2 media depleted of one nutrient followed by a spike of the missing nutrient.
Treatments:
01 Minus P
02 Minus P Spike
03 Minus Si
04 Minus Si Spike
05 Minus N
06 Minus N Spike
07 Replete
