The CB-25-SVS Wave Buoy by NexSens Technology offers the latest in real-time wave observations in a compact, affordable, and easy to deploy platform. At 18” hull diameter and less than 30 lb. (13.6kg) weight, it can be used for drifting, tethering or mooring applications. The buoy accurately measures wave height, period, direction, and more using SeaView Systems’ industry-leading SVS-603HR sensor, relied upon in buoy networks by NOAA and many others throughout the world. External sensor ports with wet-mate connectors support GPS, meteorological, and water quality sensors for maximum flexibility.
The buoy is constructed of an inner core of cross-linked polyethylene foam with a tough polyurea skin. A rechargeable battery with integrated solar panels power the wave buoy continuously, and all electronics are housed in a quick-removable waterproof package with wet-mate connectors. Three 1.5” pass-through holes facilitate cable routing of underwater sensors.
Available with integrated cellular or Iridium satellite communications, the CB-25-SVS Wave Buoy sends data in real-time to the cloud-based WQData LIVE datacenter. In the Basic tier, this free service allows users to securely access and analyze data, as well as share data through an auto-report. Subscription-based tiers of WQData LIVE are also available for generating custom alarms, exporting data through an API or custom NDBC/GLOS formats, and providing a publicly-accessible version of the project website.

Lufft WS800: Introducing A Station that Can Weather the Storm
The Lufft WS800 Multi-Parameter Weather Station measures a full suite of atmospheric parameters that provides all-encompassing data on the local environment, including a one-of-a-kind lightning detector. This compact, cost-effective sensor simultaneously measures air temperature, humidity, pressure, precipitation, solar radiation, lightning, and wind with an integrated electronic compass. An internal fan and heater reduce the effects of external influences for accurate measurements during long-term deployments. The sensor can be easily mounted on a 2-inch diameter pipe above any local obstructions with the included bracket mount, U-bolts, and 10-meter cable. 
 
 Settings for the unit can be adjusted using the latest UMB-ConfigTool.

Monitoring Newfound Lake's tributaries allows the NLRA to better understand how these systems are changing and helps to quantify the impact that development is having on water quality in Newfound Lake. (Credit: NLRA) 
As many resource managers and conservation groups can attest, their work serves both the environment and the surrounding communities. Dynamic and healthy ecosystems can become center points for towns, cities, and entire regions—such is the case in the Newfound Lake Region, located in central New Hampshire. The Newfound Lake Region Association (NLRA) knows just how critical the preservation of the lake and surrounding watershed is for all members of the region.
Read MoreGoing, Going, Gone: Endangered Species Recovery and Conservation
Across the planet, biodiversity and natural habitats are declining dramatically. Countless species of flora and fauna around the world are being listed as either threatened, endangered, or extinct. According to a 2019 UN Study , around one million species are already at risk of extinction. Unless action is taken to reduce the causes of biodiversity loss, many of these species could disappear within the next few decades. Invasive species, habitat destruction, pollution, and other environmental stressors are all major causes of biodiversity decline. 
 
 While high biodiversity is synonymous with places like the Amazon Rainforest and the Great Barrier Reef, it can also be found locally.
