Social mapping of Australian bays and conservation of Fish Aggregating Bryozoans

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.

What sonar do I need for BioBase mapping?

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

BioBase EcoSound Vegetation and Bottom Hardness Algorithms Improved

Sonar technology continues to improve bringing anglers and aquatic managers better, more clear pictures of the underwater environment on which they are so intently focused. Launched in 2011, BioBase’s EcoSound technology was the first cloud aquatic mapping system designed to process sonar logs from off-the-shelf Lowrance® sonar and create maps of bathymetry, aquatic vegetation biovolume, and bottom hardness for aquatic resource professionals. Today, BioBase is the leading cloud software solution for automated lake and coastal seagrass mapping.

Between 2011 and 2014, the algorithm underwent five major revisions. The bottom hardness algorithm has undergone two major revisions, with the last one in 2014.  Thus, our code base was due for an overhaul in order to maintain performance and compatibility with newer generation Lowrance and Simrad sonar. This refactoring effort was also an opportunity for us to improve the vegetation and bottom hardness algorithms. Many of these improvements also carry over sister consumer technology C-MAP Genesis, which uses many of the same algorithms and backend processing architecture

BioBase – New EcoSound Subscription Models Launched

New EcoSound Subscription Models Launched

BioBase EcoSound
Create detailed bathymetric, aquatic, and coastal habitat maps by recording sonar from Lowrance or Simrad sonar devices

At BioBase, we are delighted to announce a new subscription model for EcoSound, created to ensure all customers can make the most out of the mapping platform.

Aligned with parent company Navico’s Environmental Sustainability Mission, and to support the widespread adoption of our technology to further the goals of aquatic conservation, BioBase will be providing free subscriptions (with up to 20 GB of storage) to Environmental Agencies, Non-Profits, and Universities engaged in aquatic resource management and research.

In order to make this a smooth transition for our current subscribers, we will move anyone with an unlimited Single-User or Single-Waterbody subscription into the appropriate full-featured Habitat+ subscription with sufficient storage until their subscription is due to expire in 2021.

FREE Subscriptions for Government, Universities and Environment Agencies

Current subscribers eligible for a free subscription should notice little change outside of being eligible for additional “freemium” subscriptions for their institution

Further, Navico will also be offering discounts of up to 35% on Lowrance hardware for US-Based agencies and universities.

New EcoSat Feature: Reclassify individual vegetation polygons

EcoSat is a first of its kind semi-automated satellite imagery processing tool that’s part of the BioBase cloud mapping platform (Figures 1 and 2).  EcoSat is helping several US states and countries map and monitor the status of shallow growing aquatic vegetation and benthic habitats.  In this blog, we discuss several tips and tricks about how practitioners can maximize the accuracy and precision of their EcoSat vegetation maps.
