Buoy data analysis
This R Markdown analysis explores seasonal differences in water quality and hydrological conditions in two urban canals in Miami—Coral Gables Canal and Little River. The workflow integrates buoy sensor data, discharge records from SFWMD DBHYDRO, and precipitation data, applies basic data cleaning and seasonal classification (wet vs. dry), and uses principal component analysis (PCA) to evaluate how key biogeochemical variables—such as fDOM, salinity, conductivity, dissolved oxygen, pH, turbidity, chlorophyll-a, and discharge—interact across seasons. Seasonal differences in the PCA structure are further evaluated using Kruskal–Wallis and Dunn post-hoc tests, allowing assessment of how hydrological seasonality influences water quality dynamics in these coastal urban canal systems.
NEON EMERGE Project: Nitrate (NO3) and Turbidity (CUPE)
This project analyzes NEON surface water sensor data to explore the relationship between nitrate (NO₃) and turbidity at the CUPE site in Puerto Rico. Using R, the workflow retrieves data directly from the NEON API, applies quality filtering, and aggregates measurements to daily and monthly time scales. The analysis includes exploratory visualizations, correlation matrices, and scatter plots to evaluate how nutrient concentrations relate to changes in water clarity and sediment dynamics. The goal is to provide an exploratory framework for understanding nutrient transport and water quality patterns in freshwater ecosystems.
Sensor Data Analysis: Boston (BOS) and Atlanta (ATL)
This project analyzes high-frequency water quality sensor data from Boston (BOS) and Atlanta (ATL) to evaluate relationships between CDOM (Colored Dissolved Organic Matter) and other in situ environmental variables. Using R, I performed correlation analysis and developed multi-axis interactive time series visualizations to explore how CDOM covaries with conductivity, temperature, dissolved oxygen, pH, and optical backscatter.
The workflow emphasizes reproducibility, structured data cleaning, and clear visualization using tidyverse, corrplot, and plotly. The result is an exploratory data analysis framework that supports rapid interpretation of sensor-based water quality dynamics across multiple urban systems.
