On the Principles of Determination of Hydrological Seasons (On Exa...

By: A.I. Babkov

Summary: Oceanological characteristics change relatively slow in winter and summer but they change sharply in spring and autumn. In order to distinguish hydrological season?s dates of sharp changes of the sea water temperatures are determined when they grow and fall. The end of spring and the beginning of autumn are determined by the dates, when the velocity of temperature changes attain maximum, the beginning of spring and the end of autumn are determined by the dates o...

Baltimore County, Maryland, Navd 88 Gps-Derived Orthometric Height...

By: illiam E. Henning

Abstract: During the past decade, global positioning system (GPS) survey data have been used to establish precise relative positioning in a three-dimensional system. GPS survey methods can and have been used to replace classical horizontal control terrestrial survey methods. However, it was only during the last few years that these techniques have been applied to classical leveling (vertical control) applications. GPS-derived orthometric heights were computed for 18 monu...

The Banks : Reserve Preservation Area

By: National Oceanic and Atmospheric Administration

Excerpt: ENVIRONMENT. The NWHI area contains several seamounts that are commonly referred to as ?the Banks.? For present purposes, the Banks consist of Raita Bank; St. Rogatien Bank; the first bank west of St. Rogatien Bank and east of Gardner Pinnacles (Bank Number 7, which remains unnamed); Pioneer Bank; Southeast Brooks Bank, which is the first bank immediately west of French Frigate Shoals; and the first bank immediately east of French Frigate Shoals. On Raita Bank t...

Barometer Calibration Guidelines

By: National Oceanic and Atmospheric Administration

Excerpt: For New Barometer Installations. Here is a step by step guide for doing the calculations and deriving the new barometer coefficient using Solomons Island as an example. (1) The PBM at Solomons Island is 7330 A 1978 and is 5.172 m above Station Datum (SD). This value is obtained from RDD, as listed in the annual Project Instructions. For new stations, contact RDD. (2) Determine the barometer height above PBM. (Obtained as four decimal places from the level abstra...

Noaa Reprint of Basic Geodesy

By: National Oceanic and Atmospheric Administration

Preface: Although geodesy is the oldest among earth sciences, dating back to the Sumerians of 5000 years ago, its subject and even its name have been widely unknown. Man's present ventures into space, his commercial explorations on the continental shelves and his increasing knowledge of science and its relationship to the world around him have made him aware of geodesy's increasing contribution.

Top Tips for Preserving the Coast : A Beach-Goer's Guide

By: National Oceanic and Atmospheric Administration

Excerpt: More than half the U.S. population lives along the coast and the average American spends 10 recreational days a year at the coast. With so many people at the coast, beaches can fall victim to the strain. You can reduce the impact you have on the beach by following these tips: Stay off beach dunes and grasses. Beach dunes are the first line of defense against coastal storms and dune grass protects shoreline homes and businesses from erosion. When people walk, dri...

Barge Morris J. Berman Spill Noaa's Scientific Response

By: Gary Petrae, Lcdr.

Introduction: The T/B Morris J. Berman oil spill was the first major spill since the Oil Pollution Act (OPA) of 1990 for which the United States Coast Guard became the sole executors of the response effort. Response activities and response management were directed by the federally designated On-Scene Coordinator. This was also the first major U.S. oil spill under OPA since the development of area contingency plans. Many important environmental issues were addressed durin...

Guidance for Benthic Habitat Mapping : An Aerial Photographic Approach

By: Mark Finkbeiner

Introduction: This document, Guidance for Benthic Habitat Mapping, An Aerial Photographic Approach, describes proven technology that can be applied in an operational manner by state-level scientists and resource managers. This information is based on the experience gained by NOAA Coastal Services Center staff and state-level cooperators in the production of a series of benthic habitat data sets in Delaware, Florida, Maine, Massachusetts, New York, Rhode Island, the Virgi...

By: Watson W. Gregg

Introduction: Satellite observations of ocean color provide large-scale, repeat coverage sampling of global ocean chlorophyll that are necessary to help understand the role of phytoplankton on biogeochemical cycling, climate change, and fisheries. However, remotely-sensed data are subject to several sources of error that affect their accuracy, for example, calibration, atmospheric correction algorithm errors, uncertainties in knowledge of the atmospheric optical state, a...

Horizontal Control (Hztl) Data

By: National Oceanic and Atmospheric Administration

!!!!Introduction: For coding and processing purposes, data associated with geodetic horizontal control (HZTL data) have been divided into two groups. These are (1) field observations (OBS data) and (2) descriptions and recovery notes (DESC data). Instructions and formats for coding and typing HZTL OBS and DESC data sets are contained in Chapter 2 and Annex P. The treatment of all data normally generated in the conduct of a classical or GPS horizontal control survey is described.

Chapter 2 Horizontal Observation (Hztl Obs) Data

By: National Oceanic and Atmospheric Administration

Introduction: The purpose of this chapter is to provide detailed specifications and instructions for the coding and keying of an observation data set for a horizontal control job. As explained in Chapter 1, a horizontal control job consists of two distinct data sets which must be submitted together. The companion data set to the horizontal observation (HZTL OBS) data set discussed in this chapter is the data set which contains descriptions and/or recovery notes for the c...

Chapter 5 Vertical Control (Vert) Data

By: National Oceanic and Atmospheric Administration

Introduction: For coding and processing, the data required for geodetic vertical control (VERT data) have been divided into two sets. These are (1) observational data of elevation differences between survey points (OBS data) and (2) descriptive data including original and recovery descriptions (DESC data). Detailed instructions and formats for the coding and keying of the OBS and DESC vertical control data sets are contained in Chapter 6 and Annex P, respectively. The tw...
