  abstract = {{U}sing imagery at 30 m spatial resolution from the most recent {L}andsat satellite, the {L}andsat 7 {E}nhanced {T}hematic {M}apper {P}lus ({ETM}+), we scale up reef metabolic productivity and calcification from local habitat-scale (10(-1) to 10(0) km(2)) measurements to regional scales (10(3) to 10(4) km(2)). {D}istribution and spatial extent of the {N}orth {F}lorida {R}eef {T}ract ({NFRT}) habitats come from supervised classification of the {L}andsat imagery within independent {L}andsat-derived {M}illennium {C}oral {R}eef {M}ap geomorphologic classes. {T}his system minimizes the depth range and variability of benthic habitat characteristics found in the area of supervised classification and limits misclassification. {C}lassification of {L}andsat imagery into 5 biotopes (sand, dense live cover, sparse live cover, seagrass, and sparse seagrass) by geomorphologic class is >73 % accurate at regional scales. {B}ased on recently published habitat-scale in situ metabolic measurements, gross production ({P}=3.01 x 10(9) kg {C} yr(-1)), excess production ({E} = -5.70 x 10(8) kg {C} yr(-1)), and calcification ({G} = -1.68 x 10(6) kg {C}a{CO}3 yr(-1)) are estimated over 2711 km(2) of the {NFRT}. {S}imple models suggest sensitivity of these values to ocean acidification, which will increase local dissolution of carbonate sediments. {S}imilar approaches could be applied over large areas with poorly constrained bathymetry or water column properties and minimal metabolic sampling. {T}his tool has potential applications for modeling and monitoring large-scale environmental impacts on reef productivity, such as the influence of ocean acidification on coral reef environments.},
