Characterization of Near-Shore Marine Vegetative Habitat Throughout Fortune Bay and Bay d'Espoir (2023-2025)

Characterization of near-shore marine vegetative habitat throughout Fortune Bay and Bay d'Espoir (2023)
Data collection began in 2023, on targeted components of coastal ecosystems throughout Fortune Bay, Connaigre Bay and Bay d'Espoir to develop a baseline dataset characterizing seagrass, macroalgae and other habitats created by structure-providing species. This effort will continue through 2027. Throughout ten sites of this region, transect data are collected detailing seagrass and macroalgae species frequency, abundance, and distribution. As part of this characterization, marine sediments are documented along each transect, and in-situ water quality measurements. Additionally, pole seines are conducted at each site to collect baseline data on the presence and diversity of fish and invertebrate species present within these habitats. 1) Seagrass and Macroalgae: Distribution, frequency, and abundance of seagrass and macroalgae are monitored at ten sites. Three transects are surveyed at each site semi-annually to record seasonal growth. 2) Species Inventory: Pole seines are conducted annually at each site to collect baseline data on nearshore fish and invertebrate assemblages. If aquatic invasive species are found during a survey, they are recorded and reported. 3) Marine Sediment: Throughout each transect surveys for seagrass and macroalgae frequency and abundance, estimates of the composition of marine sediment found present and its depth along each transect are recorded at 5 meter intervals. 4) Water Quality: In-situ water quality data is collected at the beginning and end of each transect surveyed. Parameters recorded include dissolved oxygen, pH, salinity, conductivity, temperature and turbidity. 72-hour rainfall and wave conditions of the site at the time of each survey are also recorded.
This project is part of the Coastal Environmental Baseline Program Initiative under the Oceans Protection Plan of Fisheries and Oceans Canada.

《财富湾与德埃斯波伊尔湾近岸海洋植被生境特征表征（2023）》
本数据集针对财富湾（Fortune Bay）、康奈格湾（Connaigre Bay）与德埃斯波伊尔湾（Bay d'Espoir）范围内的近岸生态系统目标组分开展调查工作，旨在构建一套基准数据集，用于表征海草、大型藻类及其他结构提供型物种所营造的生境。数据采集工作于2023年启动，将持续至2027年。
本区域共设置10个调查站点，通过样线法采集数据，详细记录海草与大型藻类的物种出现频率、丰度及分布情况。作为生境特征表征工作的组成部分，沿每条样线记录海洋沉积物信息，并开展原位水质测量。此外，在各站点开展杆围网（pole seines）采样，以获取这些生境中鱼类与无脊椎动物的存在情况及多样性的基准数据。
1) 海草与大型藻类：在10个调查站点监测海草与大型藻类的分布、出现频率及丰度。每个站点每半年开展3条样线的调查，以记录其季节生长动态。
2) 物种名录调查：在各站点每年开展一次杆围网采样，以获取近岸鱼类与无脊椎动物群落的基准数据。若调查过程中发现水生入侵物种，将予以记录并上报。
3) 海洋沉积物：在每条用于海草与大型藻类频率、丰度调查的样线上，以5米为间隔，记录所在海域沉积物的组成估算值及沿样线的沉积深度。
4) 水质监测：在每条调查样线的起始与结束位置采集原位水质数据。记录的参数包括溶解氧、pH值、盐度、电导率、温度与浊度。同时记录每次调查时站点的72小时累积降雨量及现场波浪状况。
