Mesoscale variability of the Mexican Tropical Pacific using TOPEX and SeaWiFS data

open access: yesCiencias Marinas, 2006
The Mexican Tropical Pacific has oligotrophic characteristics; however, it sustains an abundant biodiversity, mainly because of upwelling promoted by its relatively shallow thermocline, strong winds and mesoscale eddies.

Chlorophyll and Chlorophyll Catabolite Analysis by HPLC [PDF]

open access: yes, 2018
The most obvious event of leaf senescence is the loss of chlorophyll. Chlorophyll degradation proceeds in a well-characterized pathway that, although being common to higher plants, yields a species-specific set of chlorophyll catabolites, termed phyllobilins.

Role of physical forcings and nutrient availability on the control of satellite-based chlorophyll a concentration in the coastal upwelling area of the Sicilian Channel

open access: yesScientia Marina, 2010
The northern sector of the Sicilian Channel is an area of favourable upwelling winds, which ought to support primary production. However, the values for primary production are low when compared with other Mediterranean areas and very low compared with ...
