Introduction to Aquatic Flow Cytometry Course

September 17-21, 2018
Bigelow Laboratory for Ocean Sciences
East Boothbay, Maine, USA

The 5-day course will include both lecture and laboratory sessions, and provides aquatic and environmental scientists and/or commercial entities an introduction to flow cytometry, including the theory of operation as well as an introduction to different flow cytometric instrumentation – analyzers (BD and BioRad) and cell sorters (BD Influx and BC Moflo Legacy) including imaging cytometry (FlowCAM).  Breakfast and lunch are provided each day and the course will also include one group dinner. Lodging is included with the course fees on our campus at our new residence hall (2017). Detailed course information and registration instructions available here.

Obituary for Marcel Robert Wernand


With great sadness, we have to inform you that Marcel Wernand passed away peacefully on Friday, March 30th 2018. Marcel was suffering from Amyotrophic lateral sclerosis (ALS), yet he kept up his good spirit and self-determination to the end.

Dr. Wernand was a marine optics expert at the Netherlands Institute for Sea Research (NIOZ) for forty years. He received a degree on Polytechnics in Math and Physical Engineering (COVALU Utrecht, The Netherlands) in 1974 and a PhD in Physics from University Utrecht in 2011. His research focus was on the study of the bio-optical variability of coastal seas and oceans using multi- and hyperspectral inherent and apparent optical properties measurements at sea and from space. Many of these instruments he designed and built himself. He developed water quality algorithms for long term monitoring using remote sensing measurements.

In 2004, he was the recipient of the Ocean Optics Conference Best Speaker’s Award (golden bell). For him, the Ocean Optics community was his scientific family and he gave another well-received presentation at the last Ocean Optics XXIII conference in 2016 in Victoria, BC, Canada, promoting the link between historic observations of ocean color and modern satellite data.

Marcel was dedicated to explaining ocean color to the public. He produced several videos explaining ocean color and its variability in time and space. As part of an larger Citizen Science project, he also co-produced the EyeOnWater-App that allows the public to share ocean color measurements based on the Forel-Ule scale using a cell phone. He also studied the history of ocean color observations from the earliest explorers to the present. He presented these in Clarity on the Sea, an e-book with a very extensive bibliography.

In addition to his scientific endeavors, Marcel was a playwright and actor, a renaissance man with wide ranging interests. Above all Marcel was a warm-hearted, humorous person who lit up any gathering with his presence.

He will be missed.

EXPORTS Field Campaign

The National Aeronautics and Space Administration (NASA) solicited proposals addressing the research needed to begin Phase I of the EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) field campaign—a large-scale field campaign that will provide critical information for quantifying the export and fate of upper ocean net primary production (NPP) from satellite observations. The overarching goal of EXPORTS is to develop a predictive understanding of the export and fate of global ocean NPP and its implications for the Earth’s carbon cycle in present and future climates.
