Bacterial abundance, bacterial organic carbon, and total organic carbon from remineralization bioassays conducted on R/V Robert Gordon Sproul cruises along the Southern California coast during July and August 2023

These data include bacterial abundance, bacterial organic carbon, and total organic carbon from remineralization bioassays conducted to assess bacterioplankton growth and DOC degradation. Experiments were conducted on cruises aboard the R/V Robert Gordon Sproul (SP2319, SP2320) between dates 2023-07-28 and 2023-08-19 along the Southern California coast. Deposition of wildfire ash on the ocean can fertilize microbial production but also has the potential to inhibit microbial growth due to heavy metal toxicity. The data collected from these field experiments can contribute to elevating understanding of wildfire-driven material transfer from the terrestrial system to the ocean and its impact on carbon and energy flow in marine food webs. These data were collected by Dr. Nicholas Baetge, Dr. Allen Milligan, Brian Ver Wey, and Parker Hansen of Oregon State University. Data were also collected by Dr. Craig Carlson, Elisa Halewood, and Keri Opalk of the University of California Santa Barbara本数据集涵盖源自再矿化生物测定（remineralization bioassay）的细菌丰度、细菌有机碳及总有机碳数据，相关实验旨在评估浮游细菌（bacterioplankton）生长与溶解有机碳（Dissolved Organic Carbon, DOC）降解过程。实验依托“罗伯特·戈登·斯普罗尔号”科研考察船（R/V Robert Gordon Sproul）开展，航次编号为SP2319、SP2320，于2023年7月28日至2023年8月19日沿南加州海岸海域开展。 海洋野火灰沉降既可促进海洋微生物生产，也可能因重金属毒性抑制微生物生长。本次野外实验获取的数据，有助于深化对野火驱动的陆地物质向海洋输送过程，及其对海洋食物网碳循环与能量流动影响的认知。本数据集由俄勒冈州立大学的Nicholas Baetge博士、Allen Milligan博士、Brian Ver Wey及Parker Hansen采集，加州大学圣巴巴拉分校的Craig Carlson博士、Elisa Halewood及Keri Opalk亦参与了数据采集工作。
