NOAA Marine Debris Shoreline Survey Field Guide 2012
Introduction	
Marine debris has become one of the most widespread pollution problems in the world’s oceans
and waterways today. The NOAA Marine Debris Program (MDP) serves as a centralized marine
debris resource within NOAA, coordinating and supporting activities within NOAA and with
other federal agencies. The MDP uses partnerships to support projects carried out by state and
local agencies, tribes, non-governmental organizations, academia, and industry.
Marine debris monitoring programs are necessary to compare debris sources, amounts, locations,
movement, and impacts across the US and internationally. Monitoring data can be used to
evaluate the effectiveness of policies to mitigate debris and provide insight into priority targets
for prevention. Thus, the NOAA MDP has developed standardized marine debris shoreline
survey protocols to facilitate regional and site-specific comparisons. This document provides a
standard data sheet and two different methods for shoreline monitoring and assessment.

Types	of	Shoreline	Surveys	
The objectives of your study will determine how you monitor for marine debris. There are two
main types of shoreline surveys: accumulation and standing-stock surveys.
 Accumulation studies provide information on the rate of deposition (flux) of debris onto
the shoreline. These studies are more suited to areas that have beach cleanups, as debris is
removed from the entire length of shoreline during each site visit. This type of survey is
more labor-intensive and is used to determine the rate of debris deposition (# of items per
unit area, per unit time). Accumulation studies can also provide information about debris
type and weight. These surveys cannot be used to measure the density of debris on the
shoreline because removal of debris biases the amount of debris present during
subsequent surveys.
 Standing-stock studies provide information on the amount and types of debris on the
shoreline. Debris within discrete transects at the shoreline site is tallied during standingstock surveys. This is a quick assessment of the total load of debris and is used to
determine the density (# of items per unit area) of debris present. Debris density reflects
the long-term balance between debris inputs and removal and is important to
understanding the overall impact of debris.

We suggest that users give careful consideration to which type of survey best suits their goals
and objectives. Table 1 provides important information to take into account when deciding how
to monitor. Once a survey type is chosen, meaningful data can be collected through regular
monitoring. The following sections describe how to choose survey sites and conduct surveys.

How	to	Pick	Your	Site	
To select your sampling site(s), follow these steps:
1. The first step is to choose an appropriate shoreline location based on the objectives of
your study. For example, if you wish to examine the impact of land use, you should select
locations in watersheds with various land use types. Next, categorize the various areas
within your location (it may help to use an aerial photo or map, as shown below). For
example, your location may cover a span of shoreline 1 km long. Within that 1 km, there
may be an area with heavy recreational use and another area where an urban stream
mouth is located. Identify any barriers to shoreline access or offshore structures that may
affect nearshore circulation (e.g. jetties).

2. Select shoreline sites (where you will sample) according to the characteristics below. If
your location includes different use areas (for example, an area with heavy recreational
use and a more remote area), it is preferable to select a site within each use category.
Shoreline sites should have the following characteristics:
 Sandy beach or pebble shoreline
 Clear, direct, year-round access
 No breakwaters or jetties
 At least 100 m in length parallel to the water (note that standing-stock surveys require a
100-m shoreline site)
 No regular cleanup activities
These characteristics should be met where possible, but can be modified.

Before	You	Begin	Your	Surveys	
Before any data collection begins, the Shoreline Characterization Sheet should be completed for
each shoreline site. On this data sheet you will note:
 GPS coordinates in decimal degrees at the beginning and end of your shoreline site, or at
the site’s four corners if the width of the beach is > 6 m;
 Shoreline characteristics (e.g. tidal range and substrate); and
 Surrounding land-use characteristics that may influence the delivery of land-based debris
to the site (e.g., farmland 5 km from a small town or urban parkland 50 m from a river
mouth).
The Shoreline Characterization Sheet needs to be completed only once per site per year unless
major changes occur to the shoreline.
Shore IDs (on the Shoreline Characterization Sheet) should be created based on the initials of the
shoreline name (e.g., Fort Smallwood = FS). This will make it easier to keep track of multiple
sampling sites.
The Shoreline Characterization Sheet and Debris Density Data Sheet were adapted from
Cheshire et al. (2009)1.
You will need the following supplies in order to complete your surveys:
 Digital camera
 Hand-held GPS unit
 Extra batteries for GPS and camera (we recommend rechargeable batteries)
 Surveyor’s measuring wheel - for standing-stock surveys only
 Flag markers or stakes
 ~100′ fiberglass measuring tape
 First aid kit (including sunscreen, bug spray, drinking water)
 Work gloves
 Sturdy 12″ ruler
 Clipboards for data sheets
 Data sheets (on waterproof paper)
 Pencils
 Trash bag or bucket - for accumulation surveys only
Safety is a priority. Do not touch or lift potentially hazardous or large, heavy items. Notify your
local officials if such items are encountered.
All of the data collection forms you will need are included in Appendix A at the end of this
document. The same data collection forms are used for accumulation and standing-stock surveys.

Accumulation	Surveys	
If you decide to conduct accumulation surveys, follow this protocol:
1. BEFORE arriving at the site, check local tide tables and plan to arrive at your site during
low tide.
2. ONCE ARRIVED, begin filling out the Debris Density Data Sheet’s Additional
Information section. Mark the beginning and end of your shoreline site, perhaps with
flags or stakes. (Remember to pick up these markers at the end of your survey to make
sure they do not become marine debris!) The back of the shoreline is where the primary
substrate (e.g., sand) changes (e.g., sand becomes gravel) or at the first barrier (e.g.,
vegetation line).
3. In order to cover the entire site from water’s edge to the back of the shoreline, decide
whether you will traverse the survey area parallel or perpendicular to the water. See
Appendix B for walking pattern schematics. If more than one surveyor is available, the
survey area should be divided evenly with clearly specified areas assigned to each
individual. Surveyors should traverse the survey area in a pre-determined walking pattern
until the entire site is cleared of marine debris.
4. Record on your Debris Density Data Sheet counts of debris items that measure over 2.5
cm, or 1 inch (~bottle cap size), in the longest dimension (see Figure 1). If any part of the
item is within the survey area, count the item. Record large debris items, anything bigger
than 1 foot (~ 0.3 m, typical forearm length from palm to elbow) in the large debris
section of the Debris Density Data Sheet.
5. Take photos of your shoreline site and some of the debris items!
2.5cm

Figure 1. Minimum debris size to be counted. *This size is required to keep surveyors counting the same
size items and to help keep the survey results uniform.

Standing‐stock	Surveys	
If you decide to conduct standing-stock surveys, follow this protocol:
1. Sketch your 100-m shoreline site and divide the 100 m into 5-m segments. There should
be 20 of them. Number each section (left to right) from 1 to 20. Each 5-m segment should
run from the water’s edge to the back of the shoreline (Figure 2). The back of the
shoreline is where the primary substrate (e.g., sand) changes (e.g., sand becomes gravel)
or at the first barrier (e.g., vegetation line).
2. BEFORE arriving at the site, select four numbers from the Random Number Table
(Appendix C) by first choosing a number between 1 and 5, and then a number between 1
4|Page

NOAA Marine Debris Shoreline Survey Field Guide 2012
and 4. The corresponding number in the table (1–20) is one of the four transects you will
survey. Complete this exercise four times to choose four random transects (each transect
can be used only once per survey). These numbers correspond to the 5-m segments you
drew on your sketch and are called transect ID numbers (see Debris Density Data Sheet).
You should fill out one Debris Density Data Sheet per transect. On any sampling day, 20
m of your 100-m shoreline site is analyzed (i.e., 20% coverage of the area). In addition,
check local tide tables and plan to arrive at your site during low tide.

3. ONCE ARRIVED, begin filling out the Debris Density Data Sheet Additional
Information section. Using your measuring wheel, begin at the start of your shoreline
section and mark the four selected transect boundaries with flags according to the
distances provided in the Transect ID table (for example, transect 12 covers 55 to 60 m
from the start of your shoreline section).
4. Measure the width of each transect from water’s edge to the back of the shoreline. Record
GPS coordinates for each transect in decimal degree format. For shoreline segments that
are less than 6 m wide from the water’s edge to the back of the shoreline, GPS
coordinates should be taken at the center (Figure 3). For shoreline segments that are over
6 m wide, take GPS coordinates at two spots—one nearer the back of the shoreline and
one nearer the water.
5. Walking each transect from water’s edge to the back of the shoreline, record on your
Debris Density Data Sheet counts of debris items that measure over 2.5 cm, or 1 inch
(~bottle cap size), in the longest dimension (see Figure 1). If any part of the item is
within the sample transect, count the item. Remember that for standing-stock surveys,
debris is not removed from the shoreline. Record large debris items, anything bigger than
1 foot (~ 0.3 m, typical forearm length from palm to elbow) in the large debris section of
the Debris Density Data Sheet.
