Environmental observations and infected host and dinospore counts in Salt Pond, Falmouth, Massachusetts, USA from 2018 through 2019

<p>Salt Pond is a shallow, seasonally stratified coastal salt pond located in Falmouth, MA and it is proximal to the labs at Woods Hole Oceanographic Institution (WHOI). This estuarine system is tidally influenced by Vineyard Sound and receives inputs of freshwater primarily from groundwater. Seasonal abiotic factors and nutrient availability in the seasonally stratified water column influence the growth and abundance of diverse microbial taxa within this system, providing an ideal setting to study syndinian parasites and host diversity temporally and across oxygen gradients. Salt Pond has anoxic waters that come within 2-3 meters of the water surface in summer and bottom waters that become increasingly sulfidic due to bacterial sulfate reduction as seasonal stratification intensifies.</p>

盐池（Salt Pond）是一处浅海型季节性分层沿海盐池，坐落于美国马萨诸塞州法尔茅斯，毗邻伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution, WHOI）的实验室区域。该河口系统受维扬德湾（Vineyard Sound）潮汐作用影响，其淡水补给主要源自地下水输入。季节性非生物因子与分层水柱中的养分可获得性，共同调控着该系统内多样微生物类群的生长与丰度，为在时间维度与氧梯度条件下研究合子虫类寄生虫（syndinian parasites）及其宿主多样性提供了理想的实验场景。盐池在夏季时，距水面2至3米的深度即可形成缺氧水体，且随着季节性分层加剧，底层水体因细菌硫酸盐还原作用而愈发富集硫化氢。
