Ocean Colour Remote Sensing of British Columbia Coastal Waters

不列颠哥伦比亚省沿海水域的海洋颜色遥感不列颠哥伦比亚省的沿海海洋是高度动态的，受到海洋学和气候过程以及大陆径流的影响。这些过程巩固了支持区域食物网的初级生产力，并决定了几种鲑鱼的栖息地，这些鲑鱼对当地经济和原住民至关重要。在不列颠哥伦比亚省，海洋动力学、环境驱动因素和鱼类资源之间的关系日益得到认识。具体而言，幼鲑鱼在其沿海迁徙路线上所经历的淡水和海洋环境的动态被认为是太平洋鲑鱼种群减少的主要驱动因素之一。提高我们对沿海海洋生物动态及其对鲑鱼种群影响的理解的基础是可以从卫星图像中获得具有足够时间和空间分辨率的数据。未来五年的研究目标是开发一个基于多卫星的框架，以提供所需规模的信息，以协助重要的生物地球化学沿海地区：不列颠哥伦比亚省沿海水域的基于生态系统的渔业管理。为了实现这一目标，我建议的研究重点是生物光学和生物地球化学数据收集，有目的地使用协同方法，包括(i)海洋彩色卫星图像和（ii）机遇船上的传感器。未来五年将解决两个短期目标：(1)优化程序，从渡轮和游轮以及固定平台上获得无人值看守的连续水上原位反射率，以验证卫星大气校正并开发基于反射率的算法，以获得海洋生物地球化学数据；(2)基于MODIS Aqua、VIIRS、Sentinel-3a和3b、GCOM-C和即将发布的PACE卫星数据，定义了BC省沿海海洋（包括陆架、内海岸和峡湾水域）的生物地球化学动力学。该研究计划将通过建立一个框架来整合来自卫星观测的数据，这些数据具有可追溯的准确性，来自研究船、机遇船和固定平台的原位数据，从而提供有关不列颠哥伦比亚省沿岸生物和非生物变量的相关时空动态的关键见解。这是了解和监测沿海系统和渔业管理需要的重要资料。该研究项目还将有助于确定与用于验证卫星替代校准的原位反射测量相关的不确定性的国际努力。此外，我将把HQP培养成具有跨学科海洋观测和管理空间科学知识的创新者，以满足加拿大现在和未来的需求。

Ocean Colour Remote Sensing of British Columbia Coastal Waters The coastal oceans of British Columbia are highly dynamic, being influenced by oceanographic and climatic processes and continental run-off. These processes underpin primary productivity that supports regional food webs and determines the habitat available for several species of salmon, which are of vital importance to the local economy and for First Nations. The relationships between ocean dynamics, environmental drivers, and fish stocks have increasingly been recognized in British Columbia. Specifically, the dynamic of the freshwater and marine environments experienced by juvenile salmon along their coastal migration routes is considered to be one of the primary drivers of declining Pacific salmon stocks. Fundamental to the improvement of our understanding of the biological dynamics of the coastal ocean, and consequent impacts on salmon populations, are data with sufficient time and spatial resolutions, which can be derived from satellite imagery. The goal of the research proposed for the next five years is to develop a multi-satellite-based framework to provide information at the needed scales to assist ecosystem-based fisheries management for an important biogeochemical coastal region: British Columbia coastal waters. To address this goal, my proposed research focuses on bio-optical and biogeochemical data collection that purposely uses synergistic methods that include (i) ocean colour satellite imagery and (ii) sensors aboard vessels of opportunity. Two short-term objectives will be addressed over the next five years: (1) Optimize procedures to obtain unattended continuous above-water in situ reflectance from ferries and cruise ships, and fixed platforms, in order to validate satellite atmospheric correction and develop reflectance-based algorithms for deriving ocean biogeochemical data; (2) Define the biogeochemical dynamic of the BC coastal ocean, including the shelf, inner coast, and fjordal waters, based on satellite data (MODIS Aqua, VIIRS, Sentinel-3a and 3b, GCOM-C, and the forthcoming PACE). This research program will provide critical insights about the relational spatiotemporal dynamics of biotic and abiotic variables along the BC coast by establishing a framework to integrate data from satellite observations with traceable accuracy, in situ data from research ships, vessels of opportunity, and fixed platforms. This is essential information for the understanding and monitoring of the coastal system and fisheries management needs. This research program will also contribute to the international effort to define uncertainties associated with in situ reflectance measurements used to validate satellite vicarious calibration. Furthermore, I will train HQP with interdisciplinary knowledge in space science for ocean observation and management to be innovators that meet the present and future needs of Canada.
