Funding body: NERC, EnvEast DTPThesis Title: Quantifying the effect of chlorophyll on upper ocean processes and regional climate.Passed Viva examination 26th Aug 2020 with minor corrections.Supervisors: Prof. Karen Heywood, Prof. Adrian Matthews, Dr. Manoj Joshi & Dr. Ben WebberProject Synopsis: Phytoplankton blooms modify sea surface temperatures by altering the absorption rate of solar radiation, which modifies ocean mixed layer radiative heating and surface heat and moisture fluxes. We are unsure as to what extent phytoplankton, at various concentrations, has on radiative heating in the Bay of Bengal (Indian Ocean) and whether we can better parameterise the effect of biological warming in coupled global climate models to improve monsoon rainfall forecasts. Ocean glider and profiling Argo float data from the Bay of Bengal Boundary Layer Experiment (BoBBLE) fieldwork campaign was used to quantify the relationship between solar penetration depth and chlorophyll concentration in the Bay of Bengal. Two thirty-year simulations using the UK Met Office’s Unified Model, coupled with the Global Ocean Mixed Layer model (MetUM-GOML), were run to investigate the effect of seasonally varying chlorophyll concentrations on summer monsoon rainfall over the Indian subcontinent. Main findings/outcomes: The depth of the mixed layer relative to the perturbed solar penetration depths controls the response of SST to chlorophyll. The largest SST response to chlorophyll forcing occurs in coastal regions. Precipitation increases significantly by up to 3 mm day-1 across coastal Myanmar during the southwest monsoon onset and over northeast India and Bangladesh during the Autumn intermonsoon period, decreasing model biases.Oral and poster presentations: European Geophysical Union 2019 (poster), Challenger Marine Society 2018 (oral), IAPSO 2017 (poster).

Associate Tutor

• Nov 2018 - Mar 2020

- Worked as an associate tutor (demonstrator) for undergraduate lectures and workshops. - I provided support for module organisers in subjects such as mathematics and environmental science. - Demonstrating mainly involved helping and supporting students undertaking experiments and analysing data that improved and developed their skills. - I explained concepts using simple and concise language in response to student questions, I encouraged students to share and contribute new ideas and I provided constructive feedback to help students achieve target grades.

Funded by BoBBLE (Bay of Bengal Boundary Layer Experiment) Attended a week-long joint UK-India workshop and review meeting with research groups such as BoBBLE, SWAAMI and INCOMPASS that are involved in monsoon research. I presented a poster of my scientific findings and engaged in networking events with other fellow researchers. The following week I collaborated with a colleague at the Centre for atmospheric and ocean Science at IISc. Together we investigated the suitability of optical measurements from Argo floats in quantifying chlorophyll concentrations in the Bay of Bengal.

• Feb 2018 - Apr 2018

On-board physicist for JC159 expedition across the tropical South Atlantic from Rio to Cape Town. The six-week cruise along 24 deg south included 20 scientists from 7 international institutions investigating the biggest threats to the oceans. As part of the physics team, our aim was to plan, monitor and sample the CTD casts at each station along the width of the Atlantic. The depths of sampling had to be decided for each cast to capture the most interesting features. This would included salinity and oxygen minimums, or nutrient and chlorophyll maximums. We helped other scientists collect water samples ready for calibration or analysis and to deploy eight Argo floats that record high resolution measurements of the top 500 m of the ocean. Meteorological data was quality controlled and analysed to see biases in relative wind calculations and PAR measurements. Our scientific aim was to better understand the uptake and loss of carbon exchanged between the atmosphere and ocean and to identify warming patterns at the ocean surface, 10 years on from a previous cruise in this region.

Investigated the impact of chlorophyll blooms on the transmission of light and radiative heating across the Southern Ocean. As part of the SOSCEX expedition in 2014, two gliders were deployed for five months south of Gough Island measuring light and biological constituents in the Southern Ocean. A new quality control process was developed to process vertical profiles of photosynthetically active radiation and to optimally determine optical parameters which could be compared to quench-corrected chlorophyll fluorescence measurements at the near surface.

Investigating the validity of using radar as a form of rainfall measurement totals compared to the Mt Office's array of rain gauges across the UK. For this investigation radar data and rain gauge data will be compared during a wetter than average June during the summer of 2016. The outcome of such a wet period resulted in a notable increase in the number of reports of water damages sent in by Severn-Trent Water customers.

Intern for EPSRC research project

• Jul 2015 - Sep 2015

I undertook a 10-week research placement in the summer of 2015, funded by the Engineering and Physical Sciences Research Council (EPSRC), within the department of meteorology under the supervision of Dr. Natalie Harvey and Dr. Helen Dacre. The aim of the project was to better understand the structural uncertainties of the Numerical Atmospheric-Dispersion Modelling Environment (NAME), used to predict the dispersion of volcanic ash following an eruption. In this study, I investigated the uncertainty in varying the model particle emission rate and changing the temporal resolution of the meteorological data, based on simulations of the 2010 Eyjafjallajokull eruption. Both variations led to implications in the overall spatial extent and internal structure of the volcanic ash plume. Thus this affected the outlined regions of hazardous ash concentrations as enforced by the UK Civil Aviation Authority.
