1 Fig. 1. Location of the study site (23-28 S, 130-140 W)
Fig.1. Location of the study site (23-28 S, W). The background image is the annual water clarity (measured by Euphotic depth, in meters, Lee et al 2007 algorithm) of 2008 (from OBPG).

2 Stations: Rrs-derived a(420) [m-1] a(420) [m-1]

Comparison between remote-sensing inversions and values determined independently by other means, all at 420 nm. (a) total absorption; (b) particulate absorption; (c) gelbstoff absorption. Values for X-axis from Table 1 in Morel et al (2007).

(b) Month-Year Month-Year Fig.3. Monthly times series of primary optical properties derived from SeaWiFS observations (1/1998 – 12/2007). (a): phytoplankton absorption coefficient (443 nm); (b) detritus/gelbstoff absorption coefficient (443 nm); (c) “particle” backscattering coefficient (555 nm). Overlaid on (a) and (b) are empirical models (open sysmbol) to highlight the seasonal and interannual dynamics. bbp(555) [m-1] (c) Month-Year

6 Chla [mg/m3] Chla [mg/m3] Month-Year Month-Year Fig.6. (a) Monthly time series of chlorophyll-a concentration derived from SeaWiFS. Blue symbol and line for Chla derived from the aph results, with the formula from Bricaud et al (2004): aph(443) = Chla (b) As Fig.3, background and intensity of Chla, with Chla from the empirical OC4 algorithm.
