Bull kelp (Nereocystis luetkeana<\/em>) is a large, fast-growing kelp that creates forage and refuge habitat for a diversity of marine life, contributing greatly to the productivity and biodiversity of coastal marine ecosystems. In 2020, Puget Sound Restoration Fund (PSRF), in partnership with several tribes, government agencies, and nonprofits, contributed to the development of the <a href=\"https:\/\/restorationfund.org\/programs\/bullkelp\/\" target=\"_blank\">Puget Sound Kelp Restoration and Recovery Plan<\/a>. To address the lack of ecological data that\u2019s limiting conservation\/restoration progress, the plan recommends monitoring kelp canopies from the surface, in combination with a widespread, systematic underwater monitoring network.<\/p>","use_case_problem_title":"Lack of ecological data to study and restore bull kelp growth areas in the Northeast Pacific","use_case_results":"Preliminary data show shifts in taxonomic identity and abundance across the spatial gradient, which hint at the utility of a broad data network to understanding ecological dynamics. PSRF anticipates that data from the monitoring network will help the team to understand the existing natural resources and species that comprise kelp beds, define the environment that will support kelp and improve the team\u2019s ability to craft meaningful hypotheses and select restoration sites, detect and interpret change as climate change and other human impacts continue to increase, and connect kelp interests within the region, and more broadly increase understanding of marine systems in the Northeast Pacific. <\/p>","use_case_results_title":"An increased understanding of marine systems in the Northeast Pacific and better ability to select restoration sites","use_case_solution":"In the summer of 2021, PSRF and partners completed surveys at eight long-term index sites (from Freshwater Bay in the Strait of Juan de Fuca to Squaxin Island in southern Puget Sound) to assess kelp forests through biological surveys. In 2023, three environmental monitoring research buoys were installed, with the goal of establishing paired surveys and environmental monitoring at each of 14 index sites with contemporary or historical bull kelp beds.   <\/p>To measure and record environmental parameters, the PSRF research team deployed Bluetooth-enabled <a href=\"https:\/\/www.onsetcomp.com\/products\/data-loggers\/mx2203\/\" target=\"_blank\">HOBO TidbiT MX2203 Temperature Data Loggers<\/a> and <a href=\"https:\/\/www.onsetcomp.com\/products\/data-loggers\/mx2501\/\" target=\"_blank\">HOBO MX2501 pH & Temperature Data Loggers<\/a>, along with optical <a href=\"https:\/\/www.onsetcomp.com\/products\/data-loggers\/u24-002-c\/\" target=\"_blank\">HOBO U24-002-C Salt Water Conductivity\/Salinity Data loggers<\/a> and <a href=\"https:\/\/www.onsetcomp.com\/products\/data-loggers\/u26-001\/\" target=\"_blank\">HOBO U26-001 Dissolved Oxygen Data Loggers<\/a> near-surface and near-bottom of the water column. Photosynthetically active radiation (PAR) sensors were also deployed to measure light, as were <a href=\"https:\/\/www.onsetcomp.com\/products\/data-loggers\/u20l-0x\" target=\"_blank\">HOBO U20L-02 Water Level Data Loggers<\/a> to measure temperature, water level, and absolute pressure (kPa) at 15-minute intervals.
