REMOTE SENSING OF TIDAL MARSH

REMOTE SENSING IS CONSIDERED TO PROVIDE QUANTITATIVE DATA ON PRIMARY PRODUCTION IN TIDAL MARSH ECOSYSTEMS. EMPHASIS FOCUSED ON: (1) DIFFERENTIATION OF VEGETATIVE TYPES (SPECIES), AND (2) ASSESSMENT OF PRIMARY PRODUCTION BETWEEN EACH VEGETATIVE TYPE (SPECIES) AND WITHIN THE DOMINANT SPECIES, SPARTINA ALTERNIFLORA. REMOTE SENSING METHODOLOGY UTILIZED SINGLE-IMAGE PHOTOGRAPHS WITH AEROCHROME INFRARED 2443 AT VARIOUS ALTITUDES. THERMAL IMAGERY WAS USED TO EXAMINE VARIOUS BANDS OF REFLECTED AND EMITTED RADIATION. IMAGE PARAMETERS AND PLANT CHARACTERISTICS WERE QUANTIFIED BY VISUAL INTERPRETATION AND COLOR DENSITOMETRY. GROUND-TRUTH DATA WAS USED TO CALIBRATE REMOTE SENSING IMAGERY. GROUND-TRUTH MEASUREMENT INCLUDED PLANT BIOMASS BY STANDARD HARVEST METHODOLOGY, STEM DENSITY, PLANT HEIGHT, SIZE CLASS DISTRIBUTION, AND PLANT PIGMENT CONCENTRATION. THE AGRONOMIC PRODUCTION ON A 46-HECTARE AREA OF SPARTINA MARSH, A 16-HECTARE SITE OF JUNCUS, DISTICHLIS AND SPARTINA AND 1142-HECTARE DUPLIN ESTUARY MARSH ARE DISCUSSED. /AUTHOR/
