Table 2. POC sinking and turnover rates.

	Area	Fast-sinking particles		Slow-sinking particles
		Sinking rate (m d−1)	k(d−1)	Sinking rate (m d−1)	k(d−1)
Initial	Onshore	171	0.35	4	13.7
	Offshore	104	0.35	9	13.7
Temp-corrected	Onshore	113.6	0.13	2.5	5
	Offshore	69.2	0.13	6.5	5

Initial (not corrected) and temperature-corrected mean sinking and carbon-specific respiration rates used to estimate microbial z* (Table 1). k estimates were made on the boundary of the on/offshore region and thus only one value is used for fast-sinking particles and one for slow-sinking particles. Applying temperature-corrections decreased sinking rates by up to 40% and k by 65%.
