Manatee Springs Run 3: Main line to Snow, Spring, and Syphon Tunnels

On 9/21/2025, KUR divers Lea Johnson, Wes Farley and Shawn Blakeslee conducted a cave dive to more than 10,000 linear ft in penetration into the cave system at Manatee Springs State Park, Levy County, Florida, USA. This dive was part of an ongoing collection of samples in the system to observe water quality parameters at different areas of the cave. Divers towed a YSI EXO3 datasonde, recording water temperature, pH, specific conductivity, and dissolved oxygen in real time throughout the dive. Grab samples of water (500ml Nalgene) were taken at predetermined locations in the cave, including the far upstream source tunnels, the Spring Tunnel (sample #6), the Snow Tunnel (sample #4) and also the Syphon Tunnel (sample #5), as indicated on the Manatee Cave System map. Sample numbers, corresponding markers placed on the dive guideline, and dive times are given to synchronize with the real-time datasonde data.

2025年9月21日，KUR潜水员利娅·约翰逊（Lea Johnson）、韦斯·法利（Wes Farley）与肖恩·布莱克斯利（Shawn Blakeslee）在美国佛罗里达州莱维县海牛泉州立公园的洞穴系统中开展洞穴潜水作业，本次潜水的洞穴穿透距离超过10000线性英尺。本次潜水属于该洞穴系统持续采样工作的一部分，旨在观测洞穴不同区域的水质参数。潜水员拖拽了一台YSI EXO3数据探头（datasonde），在整个潜水过程中实时记录水温、pH值、比电导率与溶解氧含量。研究人员按照海牛洞穴系统地图标注的位置，在洞穴内的预定点位采集瞬时水样：使用500毫升纳根（Nalgene）瓶，采样点位包括最上游的源隧道、春隧道（采样编号#6）、雪隧道（采样编号#4）以及虹吸隧道（采样编号#5）。本次研究同时记录了采样编号、潜水导线上的对应标记点以及潜水时间，以便与实时数据探头采集的数据进行同步匹配。
