Atlantic Sea Scallop Larval Recruitment Environmental Profiles from Passamaquoddy Bay 2022

Fisheries and Oceans Canada collected 62 CTD profiles across 3 sampling stations over 22 days from June to October 2022. The dataset characterizes coastal environmental conditions for scallop spawning and larval drift, including temperature, conductivity, salinity, sigma-theta, sea pressure, and depth measurements taken at weekly intervals.

Use Cases

• Analyze weekly temperature and salinity variations across the 3 sampling stations to model larval drift patterns in Passamaquoddy Bay.
• Correlate depth and sea pressure profiles with sigma-theta data to understand water column stratification effects on scallop recruitment.
• Compare conductivity and temperature time series from the Chamcook Harbour and Big Bay stations to assess site-specific environmental stressors.

Strengths

• Contains 62 CTD profiles providing detailed water column measurements.
• Data collected over a 5-month time range (June-October 2022) across 3 distinct sampling stations.
• Processed according to Fisheries and Oceans Canada's Ocean Data and Information Section QAQC procedures, ensuring standardized quality.

Limitations

• Limited temporal scope to a single season (2022), preventing analysis of long-term trends or interannual variability.
• Geographic scope is restricted to 3 stations within Passamaquoddy Bay, New Brunswick, limiting broader regional inferences.
• Sample size of 62 profiles may be insufficient for highly granular statistical modeling without aggregation.
