About Me

I am an Oceanography graduate and geospatial enthusiast with a strong foundation in remote sensing, GIS mapping, and environmental data science. My expertise spans geospatial analysis, spatial modeling, and advanced data visualization, with proficiency in tools such as ArcGIS, SeaDAS, and Google Earth Engine for satellite data processing and geographic analysis.

In addition to my technical skills, I am experienced in programming with Python and R, as well as advanced MS Excel, enabling me to apply computational, statistical, and spatial approaches to complex environmental and oceanographic datasets. I am particularly passionate about leveraging these skills to address practical challenges in coastal and urban systems, contributing to innovative, data-driven research and solutions.

Spatial and Temporal Variability of PAR, Kd490, and SST in the Bangladesh EEZ (2016–2022)

Undergraduate Project   |   Supervisor: Abu Bokkar Siddique   |   Jul 2023 - Dec 2023

Project Summary

This research investigates how Photosynthetically Available Radiation (PAR), Diffuse Attenuation Coefficient (Kd490), and Sea Surface Temperature (SST) vary both spatially and temporally in the Bangladesh Exclusive Economic Zone (EEZ) from 2016 to 2022. Using satellite-derived data (MODIS-Aqua) processed in SeaDAS and ArcGIS, the study analyzes monthly and annual trends for each parameter. The aim is to reveal how these physical factors influence marine ecosystems in the Bay of Bengal and to provide insights crucial for sustainable management amid climate change.

Key Findings

  • PAR ranged from 32.47 – 55 Einstein/m²/day with higher values offshore and seasonal highs in May–July.
  • Kd490 values indicated higher water turbidity (up to 0.33 m⁻¹) near coastlines due to runoff & anthropogenic impacts.
  • SST varied seasonally from 22°C – 31°C, revealing a subtle multi-year warming trend.

Quantitative Analysis of Annual Chlorophyll-a and Sea Surface Temperature Fluctuations in the Bay of Bengal Using Remote Sensing Data

Academic Project   |   Supervisor: Dr. Subrata Sarker   |   May 2023 - Jun 2023

Project Summary

This research analyzes the spatial and temporal patterns of Chlorophyll-a concentration and Sea Surface Temperature (SST) in the Bay of Bengal using monthly satellite data from January to December 2020. Data were sourced from the NASA Ocean Color Web and processed using SNAP and ArcMap software. Specific coastal regions near Bangladesh were selected for detailed comparison, while regional and seasonal variability across the Bay was mapped and quantified. The study aimed to enrich understanding of marine ecological dynamics and climate processes in the Bay of Bengal, providing valuable data for marine research and management.

Key Findings

  • Chlorophyll-a levels were lowest in May and peaked in August, indicating strong seasonal variation.
  • Sea Surface Temperature (SST) increased gradually from January, peaked in May, then declined after October.
  • There was a negative correlation between chlorophyll-a and SST: higher chlorophyll was found when SST was lower.

Internship

Growth, Observation, and Identification of Indigenous Marine Phytoplankton of the Bay of Bengal, Bangladesh

Bangladesh Fisheries Research Institute (BFRI), Marine Fisheries and Technology Station, Cox's Bazar

Supervisor: Zahidul Islam   |   5 Mar 2025 - 19 Mar 2025

Project Summary

This internship provided a comprehensive overview of a study focused on marine phytoplankton indigenous to the Bay of Bengal. The research encompassed the culture, growth observation, isolation, and identification of these microscopic organisms. The findings contribute meaningfully to enhancing marine biodiversity assessments and supporting effective management strategies for fisheries resources in the region.

Key Activities

  • Sample Collection & Fieldwork: Collected seawater samples from coastal waters near Laboni Beach, Cox's Bazar, using a plankton net with a 20µm mesh size.
  • Culture & Media Preparation: Prepared and sterilized glassware and utilized Guillard's F/2 media to culture the marine microalgae. Successfully isolated and cultured 29 distinct phytoplankton strains.
  • Growth Analysis: Conducted a comparative analysis of Skeletonema sp. growth in both Natural Seawater (NSW) and Artificial Seawater (ASW). The results demonstrated robust growth in NSW, while the population rapidly declined in ASW.
  • Phytoplankton Identification: Performed morphological identification of species using light and fluorescence microscopy (20x, 40x). Referenced the book 'Plankton of Bangladesh' to ensure taxonomic accuracy. Identified species from groups including diatoms and dinoflagellates.
