设计了一种自由漂浮器，用于直接测定海水中的光化学产生率、光解速率和光通量。这个漂浮器由六个托盘组成，这些托盘串联悬挂在一根浮标绳上。托盘的构造使得连接的石英容器，其中包含过滤后的海水，同时暴露在下流和上流照射下。石英容器的两端用带肋的TFE聚四氟乙烯塞子密封，允许在不引入顶空的情况下进行多次二次取样。自由漂浮器被用来研究南极水域的光化学过程。它在12-15小时的部署中表现良好，即使在持续风速在15至26米S−1之间的波涛汹涌的海面上也是如此。尽管没有在这里进行测试，但在淡水环境中的光化学过程研究中，漂移器应该也会表现得同样出色。
A free‐floating drifter was designed to directly determine in situ photochemical production rates, photolysis rates, and light fluxes in seawater. This drifter consisted of six trays that were suspended in series from a single buoy line. The trays were constructed so that the attached quartz vessels, containing filtered seawater, were exposed to both downwelling and upwelling irradiation. The quartz vessels were sealed at both ends with ribbed TFE Teflon stoppers that permitted multiple subsampling without introduction of a headspace. The free‐floating drifter was used to study photochemical processes in antarctic waters. It performed well during 12–15‐h deployments, even in rough seas with sustained winds between 15 and 26 m s−1. Although not tested here, the drifter should perform equally well in the study of photochemical processes in freshwater environments.
