This record contains satellite-sensed chlorophyll-a concentration images of the Canadian Beaufort Sea at 1.1 km resolution. The dataset consists of 276 images, aggregated into two-week composites by calculating the mean value at each pixel, comprising years 1998 through 2020. The dataset spans two ocean colour sensors, MODIS-Aqua and SeaWiFS. The Arctic Ocean Empirical algorithm was used to calculate chlorophyll-a concentration, after images were corrected for atmospheric effects using the NIR-SWIR switching algorithm, and Remote Sensing Reflectance (Rrs) were produced.

Chlorophyll-a (mg/m2) time series at the 3 fixed stations and 46 stations, grouped into transects, of the Atlantic Zonal Monitoring Program (AZMP) under the Quebec region responsibility. The mean integrated chlorophyll-a data (0-100 m) of the last ten years are displayed as 2 layers, one for the June survey (2011-2019. 2020 not sampled), another for the autumn survey (2011-2020). A third layer shows the positions of the fixed stations of the program (Anticosti Gyre, Gaspé Current and Rimouski).

MODIS-Aqua Chlorophyll-a (Chl-a) was acquired from the NASA Ocean Biology Processing Group where Chl-a concentration was calculated using the OC3/OCI method. The months of January and December were excluded from these datasets, as data in the winter months at higher latitudes are missing due to low sun angle preventing acquisition. The monthly geometric mean value at all pixels was calculated for individual years, then the geometric mean and geometric standard deviation factor of chlorophyll-a were calculated by month from these images. These methods of calculating mean and standard deviation were used due to the log-normal distribution of chlorophyll-a.

MODIS-Aqua Chlorophyll-a (Chl-a) was acquired from the NASA Ocean Biology Processing Group at processing Level-3 (version 2018), 4-km resolution, where Chl-a concentration was calculated using the OC3/OCI method. The months of January and December were excluded from this dataset, as data in the winter months at higher latitudes are missing due to low sun angle preventing acquisition. The monthly geometric mean value at all pixels was calculated for individual years, then the geometric mean and geometric standard deviation factor of chlorophyll-a were calculated by month from these images.

MODIS-Aqua Chlorophyll-a (Chl-a) was acquired from the NASA Ocean Biology Processing Group at processing Level-2 (version 2018), 1-km resolution, where Chl-a concentration was calculated using the OC3/OCI method. The months of January and December were excluded from this dataset, as data in the winter months at higher latitudes are missing due to low sun angle preventing acquisition. The pixels were aligned on a regular grid using the SeaDAS program, after which the monthly geometric mean value at all pixels was calculated for individual years. Finally, the geometric mean and geometric standard deviation factor of chlorophyll-a were calculated by month from these images.

Water temperature is considered a key ecosystem driver in freshwater ponds and streams of PEI National Park. American eel and Eastern Brook trout have been chosen for evaluating pond and stream temperature conditions as they are a common residents in most Atlantic Canada water bodies. Eastern brook trout are intolerant of warm water conditions. Stream temperature and brook trout growth are important factors that can directly influence survival, growth and distribution.

Freshwater ponds are monitored annually for fish species diversity and American eel abundance (catch per unit effort, or CUE), and American eel total length. Hoop traps and gee-type minnow traps are used to sample fish communities in four ponds within PEI National Park. Each pond is sampled over a three day period with a fishing effort of 3 trap nights in 9 different trap sectors of a pond. Species abundance is recorded for each net.

The park monitors water quality on Clear Lake by sampling total phosphorus, Chlorophyll-a, oxygen consumption in the hypolimnion, and mean total phosphorus in the inflow streams. Nutrient and oxygen parameters will continue to change due to nutrient stress levels in the lake and thus, the targets and thresholds will change.

The park monitors water quality of streams and ponds (lakes) on a triennial cycle, reporting on total organic carbon, acidity, phosphorus, nitrogen, dissolved oxygen, turbidity, and Chlorophyll A. These metrics are compiled into a water quality index (WQI) that summarizes overall water quality.

Wapusk National Park (WNP), protects a vast landscape of coastal salt marshes, countless ponds, and a diversity of boreal-tundra interface habitats, and serves as staging areas for migrating birds, including the Lesser Snow Goose (LSGO). Over the last few decades LSGO populations have increased exponentially due to multiple factors the LSGO is now considered hyper-abundant. Grazing LSGO create large disturbed and barren areas altering vegetation, soil, and ponds, and affecting the ecological integrity of the parks terrestrial and aquatic ecosystems. To assess goose impacts and their spatial expansion, thirty (30) ponds were selected to form a coarse grid covering the area north of the Broad River and east of Nestor Two camp.
