I am a biological oceanographer at NASA Goddard and a member of the Field Support Group (FSG), part of the Ocean Ecology Laboratory (OEL; Code 616). The FSG collects in situ optical and biogeochemical data for Earth science climate data records and other supporting data records used for ocean color satellite vicarious calibration, data product validation, and bio-optical algorithm development. To this end, the field support group participates in large scale field campaigns, where in situ instruments are deployed to measure the optical properties of the ocean water column as well as collect biogeochemical samples. I have vast experience participating in global oceanographic field campaigns, traveling to such areas as the Chukchi Sea, the Southern Ocean and North Atlantic. My expertise is in IOP measurments and analysis. My interests also include phytoplankton ecology and diversity throughout the global ocean and the detection of phytoplankton types using satellite ocean color data. I am also a PhD candidate at the University of Marland, College Park where my dissertation is focused upon phytoplankton ecology and optical water types in the Chukchi Sea.
Phytoplankton functional type algorithm validation
I am responsible for using phytoplankton pigments and a program called Chemtax to validate phytoplankton functional type algorithms on a regional scale. These algorithms are used to discern phytoplankton community structure using in situ and ocean color derived products.
Lead a workshop to update the NASA protocol for absorption
The absorption workshop was held June 11-13th. The overarching goal of the workshop was to produce an updated NASA protocol document that will highlight the most recent technological advances and improvements to the measurement of particle absorption. Ten experts, both local and international, from the field of ocean optics were asked to participate in the workshop based on their expertise. A subset of the attendees were asked to present current methods and technological advances for measuring particle absorption. Each participant (or group of participants) was assigned a writing task with the goal of a written protocol document by the end of the year. The group also discussed interest in future workshops, such as a workshop to address particle absorption data interpretation and applications (such as modeling and algorithm development) This document will be a living document and will be publicly available to the community. Aimee will address the details of the workshop in a poster at the Ocean Optics meeting in October thereby allowing for community comment, suggestions and, most importantly, community participation.

Poster, Ocean Carbon and Biogeochemistry Summer workshop
In situ optical and biogeochemical in- and above-water measurements are critical for calibration and validation of satellite ocean color radiometry data products, and for
refinement of ocean color algorithms. During the SeaWiFS era, NASA commissioned the development of a series of ocean optical measurement protocols, which have served
as international reference standards ever since, and have promoted the collection and assembly of climate quality, ocean optical datasets by the global ocean color
community. Over the past few years, NASA has sponsored several international workshops (sometimes in conjunction with IOCCG) with subject matter experts to update and
develop new community consensus field measurement protocols for ocean color sensor validation. Newly-drafted protocols are available to the international user
community on the IOCCG webpage for a period of time for public comment and access and associate editorial board peer-review, before they are accepted as international
reference standards. Finalized protocols receive a version number and digital object identifier from IODE Ocean Best Practices. The updated protocols are intended to be
“living” documents, periodically updated as methods and technologies advance.

Ocean optics course 2011: Instrument calibration to satellite validation
2012
A generation of viable data records from satellite-borne ocean color instruments requires complementary field data for the calibration and validation of the instruments and their data products. Production of decade-long “climate data records” from these remotely-sensed time-series requires very high quality measurements of bio-optical and biogeochemical parameters collected following well-vetted calibration, deployment, and data processing protocols. To this end, NASA recently funded a graduate-level course titled “Calibration and Validation for Ocean Color Remote Sensing.” Students were immersed in measurement theory and instrument concepts in the classroom, and they applied laboratory theory to instrument operation and data collection in the field. Comprehensive laboratory sessions combined application of the theory and hands-on experience with the instruments. The course impressed upon the students the importance of quality data collection, data processing, applying the appropriate corrections to the data, accounting for uncertainties, and quality control. This poster describes the fundamental step-by-step process that should be implemented from data collection to data submission, using instruments operated during the course as examples, and demonstrates that this program is essential to the next generation of bio-optical oceanographers.
Chromatographic method development, calibration and validation: Recognizing the importance of
performance metrics when establishing a new method.
2009
The use of pigment oceanography in mapping the productivity of the world’s oceans has become increasingly important. High performance liquid chromatography (HPLC) analysis allows oceanographers to identify and quantify pigments, thereby characterizing community composition of the word’s oceans. Phytoplankton are important as a major component of the food web, and can influence global chemical and CO
2 budgets through uptake of atmospheric CO
2 and the production of volatile compounds (e.g. DMS) that may escape to the atmosphere and influence cloud formation. Discreet quantification of Chlorophyll a (a major light-harvesting pigment) from HPLC analysis offers an overall estimate of in situ primary productivity; these measurements may be used to validate remote sensing measurements of ocean color. Identification and quantification of marine pigments provide scientists with information required to understand current community structure and dynamics in various regions of the world’s oceans. Understanding global variations in global community structure in response to climate change will allow for a better understanding of current and future global CO
2 budgets.

Johns Hopkins University Applied Physics Laboratory (JHU APL) hosts an annual “Girl Power” Science, Technology, Engineering and Mathematics (STEM) expo, a free event that encourages and informs young girls from the ages of middle school and high school who are interested in STEM careers. The event is co-sponsored by APL, the Women's Giving Circle of Howard County, and the Maryland Space Business Roundtable. The young would-be scientists were given an opportunity to speak with professional women in STEM careers, in fields including, but not limited to, computer science, electrical engineering, aerospace and information technology. Demonstrators at the event hailed from such prestigious government agencies as NASA and the NSA. TThe events include features such as a larger number of hands-on activities (e.g. building a hovercraft), a workshop on how to apply for college, and 30-minute workshops on cyber situational awareness and women in aerospace.
