Este producto de nivel 3 incluye datos de color del océano y de biología oceánica satelital producidos o recopilados en virtud del EOSDIS.
Este conjunto de datos se puede usar para estudiar la biología y la hidrología de las zonas costeras, los cambios en la diversidad y la distribución geográfica de los hábitats marinos costeros, los flujos biogeoquímicos y su influencia en los océanos y el clima de la Tierra a lo largo del tiempo, y, por último, el impacto de la variabilidad y el cambio climático y ambiental en los ecosistemas oceánicos y la biodiversidad que sustentan.
Ya se aplicaron el factor de escala y el desplazamiento.
En este conjunto de datos, faltan varias fechas de datos. Por ejemplo, faltan la mayoría de las fechas entre el 29 de abril de 2009 y el 1 de diciembre de 2009.
Los valores estimados para el POC pueden ser el resultado de que los datos se generaron sin una escala. Para obtener más información, visita SeaWiFS OceanData.
