Diel Variations in the primary productivity of the upper ocean from autonomous glider and autonomous profiling float observations

Diel Variations in the primary productivity of the upper ocean from autonomous glider and autonomous profiling float observations

Internship Description

Using autonomous gliders and profiling floats, we have investigated the interaction of physical and biogeochemical processes in the upper layers of the Red Sea. In all of these, we see distinct diel patterns of variability in key biogeochemical variables that include chlorophyll, suspended particles (particulate carbon), and dissolved oxygen. These processes represent the complex interaction of the daily solar cycle, nutrient supply, and physical processes that contribute to horizontal transport and vertical mixing of the water column. The goal of this study is to understand the diel variations in the key biogeochemical variables and determine how they are informing us about the primary productivity of the upper layer. The visiting student will work with existing data sets that we have been obtaining since 2013, and will also be able to participate in ongoing work that is currently ongoing within the Red Sea.​​

Deliverables/Expectations

1. Understand the presence and persistence of diel variability in key biogeochemical variables that have been obtained with autonomous platforms in the central and northern Red Sea.

2.   Evaluate whether it is possible from these data sets to determine if net primary production is occurring, or if the system is in a static, recycling state.

3. If the outcome of this effort is deemed successful, and meaningful, we expect to include this work within a publication in which the student can participate​.
