This Saturday June 21st, collect samples from bodies of water to catalog the ocean’s microbial biodiversity.
Want more marine-themed citizen science projects? We’ve got you covered!
This Saturday June 21st, citizen scientists will be able to take part in MyOSD (official site) the citizen science component to this year’s Ocean Sampling Day (OSD). The event is organized by Micro B3 (Microbial Biodiversity, Bioinformatics and Biotechnology) a European cross-disciplinary multi-institute collaborative aimed at developing large-scale research efforts to forward marine biodiversity research. On OSD, scientists around the world will collect water samples in an effort to catalog the ocean’s microbial biodiversity. On the same day, citizen scientists will gather environmental and contextual data. Organizers say that this ‘snap shot’ of the Earth’s waters might be the ‘biggest data set in marine research that has been taken on one single day.’
Scientists are interested in marine microbes because of the role they played and continue to play in shaping our global environment. Microbes were critical to the evolution of life on the Earth. “Microbes were the first organisms evolving on Earth. When microbes developed the ability to photosynthesize, they began producing oxygen. This transformed the Earth’s early environment, making it hospitable to life,” explains Julia Schnetzer a graduate student at the Jacobs University and Max Planck Institute and the MyOSD coordinator.
“Today, marine microbes still produce more than fifty percent of the oxygen we need to breathe and consume fifty percent of the world’s carbon dioxide. In addition they are involved in key biological processes in the ocean system such as nitrogen fixation and the carbon pump.” Nitrogen fixation increases the availability of biologically accessible nitrogen by transforming atmospheric nitrogen into ammonium. The ocean’s carbon pump is a biological cycle which removes atmospheric carbon and sequesters it into organic materials deep inside the ocean. Several gigatons of atmospheric carbon are cycled into the oceans each year. “Their participation in these processes make microbes critical in shaping the climate of the planet and thus are essential to the health of our environment.”
OSD will help scientists understand microbe biodiversity and how microbes affect the environment. On the 21st of June, teams of scientists will take water samples at various locations and identify microbial content via DNA sequencing. Marine microbes are particularly challenging to raise in culture, which has hindered their study in the laboratory. However advances in high through-put DNA sequencing technology have made it more practical and cost effective to study marine microbes directly from their natural habitat. In addition to analyzing microbe content, scientists will be taking environmental and contextual data such as water salinity, mineral content, air and water temperature.
“The results from OSD will produce two sets of data especially useful for marine scientists. The data about microbial biodiversity will help us understand which species are present and what they are doing. The environmental parameters will give us an idea on how the microbes influence their environment and how the environment influences them,” says Schnetzer. All the collected data will go into a publicly available open source repository. Researchers and citizens can visit the OSD map to see the locations and the genomic, environmental, and contextual data from the sampled sites. The website provides a helpful tutorial on farming the data.
More areas sampled mean better resolution of our ocean’s picture. OSD organizers need citizen scientists to help fill in the gaps. If you live near a body of water, you can help collect environmental information such as location, time, and temperature. Even if it is just a small nearby stream, OSD organizers still want your data. If you own water sampling devices, or are willing to build your own like a simple Secchi Disk, you will be able to provide additional useful information such as water pH or transparency. Download the free OSD app (Android and iPhone compatible) to make submitting your measurements easier. Don’t have a phone? Just save the data and submit it later online. Find out details about contributing to the project, data gathering instructions and analysis kits here.
Organizers hope that by engaging citizen scientists it will provide a better understanding of the value of our oceans and the need to protect them. “The more citizen scientists support there is for MyOSD the better the event will become and the more emphasis can be placed on the importance of education and outreach in marine science in future OSDs,” says Schnetzer.
So this Saturday, go out, get wet and get some data!

Today is World Water Monitoring Day! Participate by ordering a test kit and submitting sample data through December of this year. Also, check out the ocean of other water citizen science projects on SciStarter.
Here at SciStarter, we spend a lot of time supporting citizen science, but we also happen to be citizen scientists ourselves. In the spirit of World Water Monitoring Day, I trekked to the Charles River in Boston to grab a water sample. Barring all potential parking and trespassing violations, it was a success! Still, you might wonder, why does this sample matter? Why care about water?
I’m glad you asked. But before I dive deeper (pun intended), here are some facts to consider. An adult human is made of ~60% water. About 70% of Earth is covered by water. We need water for our metabolic processes internally and for our day-to-day tasks externally. Water is there when you shower, brush your teeth, or guzzle down a drink after a run. Water is also essential for the productivity of farms, which, in turn, provide us food. You get the picture: we need water. Likewise, so do other animals and plants, especially those that live in or near aquatic environments.
Consequently, the sample data collected and submitted by millions of people on World Water Monitoring Day not only benefit us human beings. It also helps scientists better understand a multitude of aquatic environments around the globe.
Participating couldn’t be easier. World Water Monitoring Challenge, an education and outreach program, provides kits that you can purchase and use to sample the water in your area. Here are the main concepts behind what you can test and why it’s important to do so.
Turbidity, the measure of relative water clarity. This is important when producing drinking water for human consumption and for many manufacturing uses. Turbid water may be the result of soil erosion, urban runoff, algal blooms, and bottom sediment disturbances caused by boat traffic and bottom-feeding fish. (You can even make your own secchi disk to measure turbidity.)
pH, a measurement of the acidic or basic quality of water. Most aquatic animals are adapted to a specific range of pH level and could die, stop reproducing, or move away if the pH of the water varies beyond their range. Low pH levels can also allow toxic compounds to be exposed to aquatic plants and animals. pH can be affected by atmospheric deposition (acid rain), wastewater discharge, drainage from mines, or the type of rock in the surrounding area.
Dissolved oxygen levels. Natural water with consistently high dissolved oxygen levels is most likely to sustain stable and healthy environments. Changes to aquatic environments can affect the availability of oxygen in the water. High levels of bacteria or large amounts of rotting plants can cause the oxygen saturation to decrease, which affects the ability of plants and animals to survive in and around it.
Water temperature. If temperatures are outside an organism’s normal range, the organism could become stressed or potentially die. Temperature also affects the rate of photosynthesis in aquatic plants as well as their sensitivity to toxic wastes, parasites, and disease. Furthermore, water temperature can affect the amount of oxygen water can hold (cold water holds more oxygen than warm water).
This project is ideal for anyone who lives near a water source, educators who want ideas to teach students about water chemistry, or citizen scientists hoping to contribute to an increasingly important field of research.
It’s the perfect project to illustrate that when it comes to citizen science, you can dive right in.

This post is part of this week’s featured projects about water quality monitoring. Take a look!
Despite over 70% of the Earth’s surface being covered in water, one in nine people do not have access to an improved water source.(1) Contaminated water kills more people than all wars, crimes and terrorism combined yet more people have a mobile phone than a toilet.(1,2,3) Every day, on our way to work or school or play, we encounter local water supplies, subconsciously noting their health. Could improving water quality be as simple as snapping a photo on your smart phone?
Creek Watch was developed by IBM research – Almaden, in consultation with the California Water Resources Control Board’s Clean Water Team, to empower citizen scientists to observe and monitor the health of their local watersheds. According to Christine Robson, an IBM computer scientist who helped develop Creek Watch, “Creek Watch lets the average citizen contribute to the health of their water supply – without PhDs, chemistry kits and a lot of time.”
Watersheds, land where all the water in creeks and streams drain into the same aquifer, river, lake, estuary or ocean, surround us. Conservation biologist Erick Burres of California’s Citizen Monitoring Program: The Clean Water Team explains, “Creek Watch as a learning tool introduces people to their streams and water quality concepts.”
Once the free iPhone application is downloaded, citizen scientists are asked to take a photo of their local waterway and answer three simple questions: What is the water level? (Dry? Some? Full?) What is its rate of flow? (Still? Slow? Fast?) And, how much trash is there? (None? Some? A lot?) The photo, GPS tag, and answers are then uploaded in real-time to a central database accessible to water experts around the world. Water resource managers track pollution, develop sound management strategies for one of our most valuable resources, and implement effective environmental stewardship programs.
Since its launch in November 2010, over 4000 citizen scientists in 25 countries have monitored creeks and streams, providing invaluable information to over-extended water resource managers; water quality data that would otherwise be unavailable. Watershed biologist Carol Boland is using this data to prioritize pollution cleanup efforts in San Jose, California. Similarly, local citizen scientists are comparing their observations to previous years as well as data collected around the world on the Creek Watch map to help inform local voluntary stewardship programs.
Creek Watch is increasing global awareness about watersheds and environmental protection. This is just the beginning. Future applications will allow citizens to monitor every aspect of their surroundings – from urban services to wildlife distribution, noise pollution to air quality and even global warming; in order to solve some of the biggest challenges of our day.
Join thousands of citizen scientists monitoring our planet’s water supply as you head to work, school, and play this week. Could your picture save a thousand streams?

This post is part of this week’s featured projects about water quality monitoring. Take a look!
Clean water. We all need it. It is necessary for human health, food security, economic growth, and preservation of natural habitats. Sadly, human activity often threatens water quality. Tracking water quality is a crucial step is maintaining safe water. It is also a huge effort.
Across the nation, individuals volunteer their time to monitor the waters in their local streams, bays and waterways. Monitoring activities include testing water chemistry, species surveys, physical assessments of watershed characteristics and surrounding habits, among others. The data collected enable researchers, policymakers, watershed organizations and local citizens to understand how our activities affect water quality, an important step learning how to protect these valuable resources.
With so many individual groups, understanding and implementing training and testing is a challenge. Recognizing this, the Extension Volunteer Monitoring Network was established. By increasing support and communication between groups, the hope is to build a cohesive “best practices” handbook for current and future groups. The network has made a significant push to help groups to get started, and to build the capacity of existing groups. Already, their website is rich with resources on training guides, equipment suggestions, to validation studies which individual groups can use to grow and develop their efforts.
Most recently, the project launched a completely updated online directory of volunteer water monitoring programs in the United States. Their directory map provides links to over 400 programs which represent 1800 different water monitoring initiatives. All programs listed were contacted to ensure they were still active and previously unlisted programs were added as well. The website also has a list of the monitoring programs.
Here at SciStarter, we have a number of water-related programs that are certainly worth checking out. Here is a small sample:
Creek Freaks – Participants gather information on stream health, posting the information on an interactive map.
Great Lakes Environmental Monitoring – Help monitor water quality around the Great Lakes.
Wading for Water Sticks – Volunteers study water sticks insects and their water environments.
Marine Debris Tracker – A mobile app that tracks debris along your local coastline or waterway.
SeaNet – Volunteers measure the effects of offshore developments on seabirds
Secchi Dip-In – Annually in July, participants are asked to take a transparency measurement in a local waterway. (Deadline for this year was July 21.)

Calling all water monitoring groups! It is time for the annual Secchi Dip-In. From now until July 22, volunteer and professional water monitoring groups are being asked to take transparency measurements in a local body of water.
A secchi disk is a common tool for measuring water turbidity, or water cloudiness. Turbidity is caused by small particles suspended in the water and is a reflection of water quality. To take turbidity measurements, on a calm and bright day the user lowers the disk into the water until the disk is no longer visible. The depth of the disk is used to calculate turbidity. Land erosion from construction or mining, pollution run-off or increases in algae all lead to higher turbidity.
Started in 1994 at Kent State University, Ohio, the Dip-In always takes place during the first few weeks of July. Participants only have to take one transparency per body of water with their secchi disk. The project helpfully provides links for purchasing disks if you do not already have one.
While project organizers prefer that measurements are taken during the “official” dip-in period, participants are welcome to add data from anytime of the year as well as past years. Currently over 2,000 water bodies are being tracked, most of which are in North America. The data are accessible to anybody interested.
In addition to transparency measurements, participants are asked to give their general impressions of the water quality as well as the area’s general aesthetics and recreational properties. These qualitative data help project researchers ascertain the potential sources affecting water quality.
