Introduction

Background of Standard Revision and Technological Evolution

Comparison Dimensions	2000 Edition	2017 Edition	Evolution Characteristics
Total Number of Terms	187 items	214 items	27 new items such as outer arc island and closure depth
Classification System	5 Chapters	6 Chapters	Added an independent chapter on "Marine Hazard Geology"
English Corresponding Words	Single Definition	Multiple versions of the specification	For example, the word "oceanic/marginal/seafloor trench" has been added.

Analysis of the core terminology system

1. Coastal landform classification system

Bedrock coast and Sandy coast Definition criteria:

Material composition: Bedrock coast requires exposed bedrock accounts for ＞70%
Dynamic characteristics: Sandy coast is mainly formed by wave action
Typical case: Comparison between the bedrock coast of Shandong Peninsula and the sandy coast of Beidaihe

2. Key terms for submarine structures

Terms	Definition points	Technical parameters
Continental shelf	Shallow sea area where the land extends naturally to the sea	The place where the slope changes suddenly at the outer edge, with a maximum extension of 200 nautical miles
Mid-ocean ridge	Underwater mountain range at the discrete boundary of plates	The total length is about 80,000 kilometers worldwide, with an expansion rate of 1-20cm/year

Standard implementation recommendations

Application specifications in marine surveys

Geological sampling reports must strictly adopt standard terms (such as Gravity column sample should be marked as "marine drilling")
Terrain description follows the submarine landform classification system in Chapter 2.8
Hazard geological assessment refers to the quantitative standards in Chapter 5 (such as coastal erosion rate classification)

Note: When used in conjunction with GB/T 15918-2010 "Comprehensive Terminology of Oceanography", the special definitions of this standard shall be used first
