| Iver2 -- Third Generation Iver AUV
|
| A powerful system for collecting water quality data
has been jointly developed by OceanServer Technology, and YSI
Environmental. The OceanServer Iver2 AUV, has been instrumented
with YSI Environmental’s proven 6-Series Sensors, to provide
researchers and scientists a complete solution (EcoMapper) for collecting
and logging data from up to 10 water quality sensors. The
vehicle is designed to travel over a wide area without support
from a workboat or associated staff for rapid water quality and
bathymetry mapping applications. Intuitive Mission
Planning Software allows a single user to quickly design and
execute survey missions, and later retrieve the geo-referenced
data for post processing or analysis in YSI EcoWatch® for
Windows® software.

MISSION PLANNING SOFTWARE – Intuitive GUI Interface
- Simple to use waypoint-based navigation and mission planning
- Select any NOAA or USGS Chart in GEO/NOS format (even geo-referenced satellite images)
- Operator selects measurement depths, speed, sensors, poling frequency, etc.
- Software creates data files to run the mission and organize logging for easy retrieval
- Programmed surveys can be terminated or modified anytime the vehicle surfaces
- Easily reconfigurable for new missions or sensors (defined software interfaces)

Example
Mission ~ Dissolved Oxygen (DO) Data Following
a mission, the data from the Vehicle can be quickly
downloaded and processed to provide water quality
information. Below is an example of the dissolved
oxygen data collected from the mission shown. On the left
side of the bottom image you can clearly see the plume
from the outflow pipe and how it enters and mixes into the
reservoir. | | |
