Floating Kelp Linear Extent
A New Statewide Spatial Data Synthesis Project
Floating Kelp (Bull Kelp Nereocystis luetkeana and Giant Kelp Macrocystis pyrifera) spatial data in Washington is comprised of a patchwork of datasets that use different methods and exist across different time periods. The last state-wide survey of floating kelp was conducted between 1995 and 2000, and kelp distribution has changed significantly since then. For researchers, resource managers, and conservation practitioners, this represents a critical data gap. As a Nearshore Ecologist at the Washington State Department of Natural Resources, I had an opportunity to fill this gap.
I synthesized 12+ floating kelp data sources to generate a new synoptic view of floating kelp across the state. I built on existing data structures to maximize compatibility with other DNR datasets. I used python scripting to automate the analysis workflow and ensure ease of future updates and data additions. The resulting datasets are presented using a suite of Esri communication tools, including an Experience Builder, Dashboard, and StoryMaps packaged neatly together to enable non-GIS users to access and interact with this important new floating kelp spatial dataset. The resulting database and web tool is being used by resource managers, policymakers, and planners to inform kelp forest management throughout the state of Washington.

I used the Vector Tile Style Editor to create a custom basemap to use across the application. I also drew customized icons by hand that dynamically populate an html/css formatted pop-up to add more visual interest and clear communication of the data.
I created a detailed User Guide which includes many figures and maps, some of which are shown here.
