The term “Fit for Purpose” has recently become a popular term in our circles in the context of mapping and surveying water bodies, and it refers to utilizing the appropriate equipment, methods, and budget for the task at hand.

This principle acknowledges that one type of equipment and method may not be suitable for every scenario. For instance, whether you’re assessing the storage volume of municipal stormwater ponds or maintaining a river channel for commercial navigation, the required level of accuracy will and should be different. While high accuracy and precision may be crucial for certain projects, it might not be necessary for others.

Professional Spotlight: Santa Cruz Harbor Sediment Mapping

Blake Anderson is the harbormaster at the Santa Cruz Harbor in California. As harbormaster he oversees all the operations of the harbor, harbor patrol staff, which includes search and rescue, law enforcement and public safety. He also oversees administration of about 1000 boat slips and day to day operations of the harbor. 6 years ago, Blake was faced with the challenge of rapidly mapping the constant shifting sand shoals in the harbor and turned his attention to BioBase as a potentially rapid mapping system

What Sonar Do I Need for BioBase Mapping? – Updated

What kind of sonar hardware should I buy for BioBase Mapping is the most common question we are asked. Admittedly, continual change in technology, products, and features can be intimidating and sometimes confusing. With this blog, we focus on what you need to know to get started with BioBase. We start with the Portable BioBase Kit – an off-the-shelf portable solution that has everything you need

Professional Spotlight – Power Plant Biologist

Professional Spotlight BioBase

For this Professional Spotlight the BioBase team sat down with a biologist at a power plant. They use BioBase to evaluate risk of cooling water intake blockage from aquatic vegetation.  This is one of many methods they use ensure abundant cooling water is available for the redundant intake systems.   In 2012, invasive zebra mussels invaded the system and paved the way for aquatic vegetation by clearing the water.  They map aquatic vegetation during the growing season and use the polygon tool to measure percent area covered and biovolume in the areas of interest.  Aquatic vegetation management recommendations are based on this data.  Before BioBase they took samples using a rake to determine what species were present and estimate the total biovolume. Now using BioBase they can easily measure biovolume at location with ease.

When asked why they chose to use BioBase they responded, “the value, there are a lot of options out there, most are expensive, but BioBase is not.”  Even at a low cost “it still produces very reliable data, BioBase is a high value product.”

BioBase Troubleshooting Lowrance Sonar and GPS Source

Too commonly we get files uploaded from customers that had either no sonar information or no GPS location in the file. This is typically due to some unit malfunction or user oversight of a disabled setting. If there is no GPS position or no sonar depth in the file, not surprisingly BioBase cannot create a map.  Here we show some of the most common troubleshooting tips and tricks that will help you diagnose common issues with newer generation Lowrance and get you back to BioBasing on the water.

Subscription Update – Single Waterbody

BioBase now offers a single waterbody subscription, it includes unlimited uploads to a single waterbody for 30 days and up to 10GB of storage for $399. The BioBase team has listened to your feedback on the single use plans and expanded it to a single waterbody. This feature now allows occasional, project-based users the ability to purchase a short-term full-featured plan on one waterbody without the commitment to a full unlimited subscription. You can purchase the single waterbody subscription through the “My Account” page then “Purchase New Subscription” link.

Professional Spotlight – Dr. Chris Harrod and Chilean Kelp Mapping

Professional Spotlight

The Professional Spotlight series is a deep dive into the global BioBase community where we highlight the unique ways sonar driven mapping is assisting research, conservation and sustainability.

The BioBase team sat down with Dr. Chris Harrod for a look into how he uses BioBase. Chris (from the UK) is a full professor of Fish and Aquatic Ecology at the University of Antofagasta in Antofagasta, Chile. He does a mixture of research, teaching, and administration tasks but our interest with him was the applied research techniques for which he was using BioBase. His research is focused on a macroalgae called kelp (aka seaweed) and its importance as a source of food/energy to fish and invertebrates in the coastal zone. He is also interested in how kelp can function as habitat, food, an anchor of sediment and even slow the turbulent waters of the Pacific Ocean.

Mapping and avoiding dense weed beds to get an edge while yacht racing

By Herb Garcia

Sailing enthusiast and BioBase Ambassador

Lake Minnetonka is one of the largest and most heavily used recreational lakes in Minnesota and is composed of an interconnected system of bays (Figure 1). Every summer, a rooted invasive aquatic plant, Eurasian watermilfoil creates thick bottom to surface mats in many areas of the lake. While these mats may occur anywhere on the lake, they generally are thickest in certain shallow areas such as the Diamond Reef area in the main lake of Lake Minnetonka (officially described as Lower Lake North). This reef is popular with anglers, power boaters, and sailors. On any given night or weekend, well over a hundred keelboats may take part in regular club racing events or regattas here. World class level sailors, including Olympic champions, America’s Cup, and other accomplished sailors regularly race on the lake and the competition can be intense. When competition is tight, every advantage is important.

Figure 1. Lake Minnetonka; a popular recreational and fishing lake just west of the Twin City metropolitan area of Minnesota. The red box highlights an area popular with boaters, anglers, and sailors. The blue contoured areas represent areas uploaded and processed by anglers using the Genesis mapping service and aggregated into the C-MAP social map. Social maps can also be viewed in the C-MAP App.

Social mapping of Australian bays and conservation of Fish Aggregating Bryozoans

Guest Blog By Dr. Adrian Flynn(a) and Dr. Travis Dutka(b)

The waters of Western Port in southeastern Australia are a recreational fishing haven and hidden beneath its turbid waters, a unique fragile seafloor community has been newly described.  Here, bryozoans, skeleton-forming filter-feeding organisms also known as ‘lace corals’, form expansive areas of reef that support a high diversity and abundance of macroinvertebrates important to snapper and other prized recreational fish species.

Figure 1: Underwater imagery of the bryozoan reefs revealed remarkable biogenic reef structures with abundant invertebrate life surrounded by large areas of bare sediment.
