You may choose to only use some of the forms for your data submission depending on
time available and the focus of your project. If you have no access to internet
during your Deep Dive, you can use our Excel registration form that follows the same
structure as the Data Portal and submit the data afterwards.
Note that some of the data requires in-depth knowledge of fisheries or other
sectors. You will find additional photos and videos for your assistance in the Data
Portal when registering the data. You can also invite relevant experts to contribute
to your Deep Dive.
FORM 1 Beach info
This is the only mandatory step to provide detailed information about the cleaning action and location during which the Deep Dive litter is collected.
FORM 2 Container Deep Dive
You will determine a distinct type and nationality of containers. The age of the items will also be recorded or estimated.
The container deep dive category is developed because many containers carry information that can link the items to a specific source due to the type of item, age or nationality (see for example Ryan et al 2019 ). The age of the item, for example, is useful to determine if poor waste management is an on-going practice. Oil and chemical containers found in Arctic Norway have been linked to maritime industries, and the nationality of household containers indicate that they origin from vessels operating in the region (Falk-Andersson and Strietman 2019) . Note, however, that information on the nationality of items should be interpreted with caution as a product can be bought in one country and discarded in another (Veiga et al. 2016).
FORM 3 Net Deep Dive
The type of fishing net and likelihood of them being discarded will be determined.
Gillnets are separated out from other types of nets, and you will analyse individual pieces of nets to identify if they are cut-offs after repairs or nets that have been damaged.
Deep dives at Svalbard have been able to identify that the majority of nets found are cut-offs discarded after trawl repairs (Falk-Andersson and Strietman 2019) . You may also record the specific fishery the nets originate from. Only do this if you have this information or have the competence to make a correct identification
FORM 4 Litter context
Beach litter is analysed based on the context it is found as this can give useful information on the likely origin of litter items (Tudor and Williams 2004).
FORM 5 Litter weight
Counting and weighting all the items individually is time consuming, thus weight will be registered according to the generalized “weight categories”.
Examples of weight categories are “domestic”, “fishery” and “food”. If you have followed Step 1 and 2, you have sorted the litter into their respective weight categories in the beginning of the Deep Dive.
Established beach litter protocols only document the number of items of the different litter categories. Thus, a large piece of a fishing net and a small water bottle have the same weighting. Decision makers may be interested in knowing the relative weight different sources of litter make up in order to prioritise management measures
