# Introduction

## Current Scientific Hydrography Practices
- Ship-Based Sonar (~5 m resolution)
- AUV sonar (1m resolution)
- ROV investigation (poor position estimation)

## Problem
- Current systems do not provide enough detail to observe small-scale change in practical time periods.
- A domain of survey exists still in the sub-meter space that traditional ROVs are often not equipped to handle. 

## Multi-Sensor Hydrography
- Through combined use of high detail sensors, composite surveys can yield scientifically significant results.
