Overview
The Vaisala WSP152 Surge Protector is a compact transient overvoltage suppressor designed for the protection of the USB connection of a PC connected to the Vaisala WXT520 or WMT52. The WSP152 is designed to protect the host PC against surges entering through the USB port. Please note that the USB connection of a PC is for indoor use only.
Mechanics
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 the earth. The WSP152 also includes noise filtering against HF and RF interference.
Applications
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 strikes.

Monitoring and Facilitating Habitat Restoration Efforts in the Great Lakes
While human infrastructure, urbanization, and industrialization have advanced human societies, the natural environment has suffered due to constructed impediments and deteriorating architecture. In order to combat this degradation, habitat restoration programs across the US work to remove impairments and improve damaged waterways.

Sustainable Fishing in Alaska: Protecting the Salmon Capital of the World through Research
In the far north, the Alaska Peninsula stretches away from the Last Frontier into the Pacific Ocean. A narrow strip of land dotted with freshwater lakes and intruded upon by ocean inlets–this unique region is intimately connected with the surrounding water. Nestled halfway down the peninsula's southern coast are the small villages of Chignik. The area has historically been home to the Aleut people and has been heavily reliant on fishing for centuries. Home to commercial and subsistence fishing today, Chignik continues to rely upon the salmon returns to the surrounding villages, which are supported by scientists working tirelessly to understand and steward these fish populations.

NexSens X3 Data Logger Review
Extreme environments meet extreme design with the NexSens X3 Data Logger . The new logger offers the latest in real-time monitoring technology with wireless communication, a large plug-and-play sensor library and ultra-low power consumption, all in a waterproof marine-grade housing. The X3 is built to handle harsh weather, floods, high winds and rough seas, and it stands alone; no additional protective housing needed. With an operating temperature that ranges from -40°C to 70°C, the logger can withstand arctic environments and extreme heat. A conformal coating on the internal circuit board isolates it from moisture and humidity.
