Vaisala WSP152 Surge Protector
- Designed to protect the USB connection of a PCconnected to the Vaisala WXT510 or WMT52
- Excellent three-stage, transient surge protection

|WSP152||Surge protector for host PC (e.g. USB connection). Includes M12 connectors. For use with 220782 and 215952.|
|220782||RS-232/485-to-USB cable adapter with 8-pin M12 female connector, 1.4m|
|215952||8-pin M12 cable with female & male connectors, 10m|
The Vaisala WSP152 Surge Protector offers three-stage protection against surge currents up to 10 kA that may enter through the USB cable or the port. The WSP152 has four channels, two of which are dedicated to power lines and two for data lines. Each channel uses a three-stage protection scheme as follows: first there are discharge tubes, then voltage dependent resistors (VDR), and finally transient zener diodes. Between each stage, there are either series inductors or resistors. Both differential and common mode protection is provided for each channel: across the wire pairs, against the operating voltage ground, and against earth. The WSP152 also includes noise filtering against HF and RF interference.
Vaisala recommends using the WSP152 when USB cables are used for permanent connections. The surge protector is always recommended when there is an elevated risk of lightning strike.

The National Oceanic and Atmospheric Administration (NOAA) and the Pacific Islands Ocean Observing System (PacIOOS) at the University of Hawaiʻi at Māno a , in collaboration with other partners, recently deployed a new ocean acidification (OA) monitoring site in Fagatele Bay National Marine Sanctuary , American Samoa. Derek Manzello , a coral ecologist with NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) in Florida, is the lead PI of ACCRETE: the Acidification, Climate and Coral Reef Ecosystems Team at AOML. Dr. Manzello connected with EM about the deployment.
“ACCRETE encompasses multiple projects that all aim to better understand the response of coral reef ecosystems to climate change and/or ocean acidification,” explains Dr.Read More
Around the world, extreme wave heights and ocean winds are increasing. The greatest increase is happening in the Southern Ocean, according to recent research from the University of Melbourne , and Dr. Ian Young corresponded with EM about what inspired the work.
“Our main interest is ocean waves, and we are interested in wind because it generates waves,” explains Dr. Young. “Ocean waves are important for the design of coastal and offshore structures, the erosion of beaches and coastal flooding, and the safety of shipping.”
Waves also have a role in determining how much heat, energy and gas can be trapped in the ocean.
“The major reason why changes in wave height may be important is because of sea level rise,” details Dr. Young.Read More
All year long the US Geological Survey (USGS) in North Dakota and South Dakota monitors water levels, but during times of flooding, all eyes are on the team. EM spoke to USGS data chief Chris Laveau about the monitoring efforts.
“The US Geological Survey in North Dakota and South Dakota is one entity, so we monitor the flooding in both states,” explains Mr. Laveau. “The role is to provide continuous information on water level, we call that gauge height or stage, and we also provide continuous information at a lot of locations on stream flow, typically called discharge. We do that year round but, obviously, during a flood event it garners more attention.Read More
