Field working in the Keys Marine Laboratory ,Florida , USA

Working in the Marine Ecology Lab

This is Dr. Douglass's Ecological lab. I spent about 86 hours in the last fall 2019 semester. I worked on Benthic Samples and sorting with four graduate students of the Florida Gulf Coast University.

Leadership program

The Social leadership Hackathon is a half-day workshop where students from diverse backgrounds can come together to learn and exercise leadership to solve a problem in their community. Participants will work in small groups to focus on a particular local problem and work together as a team to create an action plan to solve it.

Atlantic Ocean !

I love Oceand and its Weather. I dived into the Ocean.

Snorkeling in the Gulf of Mexico

This was part of our Marine Ecology course. we collected fish and seagrass samples from different spots of the Gulf of Mexico. then We identified all of them at the Laboratory.

Community Ecology

Community Ecology :study of the interactions between species, such as mutualism, predation and competition, and the dynamics and structure of the community. I did some analyses on Nonmetric multidimensional scaling using R.

CNN_MarineMammal_Prediction

This is a basic Marine Mammal and Sharks detection-based on convolutional neural network model from static images. The classification stage is now complete; after some months, I will update the entire code for mammal and shark detections. At first , I used VGG-19 pretrained CNN model, then I built a new simple CNN model. The convolutional Neural Network CNN works by getting an image, designating it some weightage based on the different objects of the image, and then distinguishing them from each other.

Ocean Simulation Modeling

Ocean models are numerical models with a focus on the properties of oceans and their circulation. Ocean models play a large role in aiding our understanding of the ocean's influence on weather and climate.I love to work in the Ocean Modeling . I have little experience in Regional Ocean Modeling system by scientists to better understand the earth climate system.

Why do we need to Model Ocean?
Ocean models play a large role in aiding our understanding of the ocean’s influence on weather and climate. They are a repository for mechanistic theories of how the ocean works with numerical methods used to transform the mathematical expression of the theories into a computational tool for scientific investigations. In particular numerical models are for hypothesis-driven experimental and theoretical studies that make them an essential tool in the hierarchy of methods used by scientists to better understand the earth climate system.

Ecosystem modeling is the mathematical representation of ecological systems from individuals to the whole biome which is studied to understand the real nature, the models can be analytic or simulations based. It has applications in a wide variety of disciplines.

Cross sectional plot of the Indian Ocean

Cross sectional Plot: A section plot is a vertical "slice" through the ocean, along an alignment that is often a straight line, portraying the vertical structure of a selected property along the alignment. this type of plot is extremely useful in the case of multidimensional data analysis. I made it using Python programming for the presentation purpose.

Mesoscale Eddies Extracted from Satellite Data

Have you noticed that offshore, the eddies are warm, while near the River mouth, water is cold and lower SLA values

Mesoscale Cyclonic Eddies those are longer 10 weeks

Mesoscale cyclonic eddies (cold core) are though known to enhance the phytoplankton biomass in the Bay of Bengal, their contribution to the carbon export to the deep ocean are yet to be quantified.Eddies exist principally in the western Bay of Bengal and most of them propagate westward. The polarity distribution of eddies shows cyclones prefer to occur in the northwest and south of the Bay of Bengal, while anticyclones mainly occur in the east of the bay.

GIS and Remote sensing

Remote Sensing (RS) has a wide range of applications in the field of physical, biological, coastal, and satellite oceanography. RS in Oceanographic research is the collection of oceanographic, monitoring of coastal and oceanic processes data, and analysis of various processes using space-borne and airborne sensors.

Each year in Bangladesh about 26,000 square kilometres (10,000 sq mi) (around 18% of the country) is flooded, killing over 5,000 people and destroying more than seven million homes. During severe floods the affected area may exceed 75% of the country, as was seen in 1998. This volume is 95% of the total annual inflow.

Application of remote sensing data in Oceanographic Research

Some important variables from Remote sensing Data

Dhaka is the capital of Bangladesh.More than 19.5 million people live in Dhaka, the capital of Bangladesh. That's more than 23,234 people per square kilometer. most of the confirmed Covid-19 case are from this area

St. Martin's Island is a small island in the northeastern part of the Bay of Bengal, about 9 km south of the tip of the Cox's Bazar-Teknaf peninsula, and forming the southernmost part of Bangladesh. it is enriched with numerous marine biotic and abiotic resources including many species of commercial fishes, coral reefs, marine algae, mollusks, etc. that has been playing a significant role for the socio-economic development of the islanders. the social-economic conditions of the local community are completely dependent on both Marine resources and tourism.

Sundarbans is the largest natural mangrove forest in the world. It lies between latitude 21° 27′ 30″ and 22° 30′ 00″ North and longitude 89° 02′ 00″ and 90° 00′ 00″ East and with a total area of 10,000 km2, 60% of the property lies in Bangladesh and the rest in India .
Image classification methods
Random forest(RF) is a supervised learning algorithm.The "forest" it builds, is an ensemble of decision trees, usually trained with the “bagging” method (Breiman, 2001).This algorithm is used for satellite image classification using google earth engine and landsat 8 imageries. Breiman proposed RF in 2001 for classification and clustering. RF grows many decision trees for classification. To classify a new object, the input vector is run through each decision tree in the forest
