Nasal discs are a type of marker that are helpful when resighting nesting females. Since spectacled eiders are sitting on their nest, incubating, the tarsal bands are not visible. Nasal discs allow for researchers to ID the female without disturbing the female during incubation.

Data from one aerial observer's sketch map were transferred to the other. The final map with both observers' reconciled data was called a master map. The data on the master map was then traced onto geo-referenced mylar quads, scanned, and attributed.
Note: This paper sketch map process was used in Oregon and Washington from 1947-2002. In 2003 the Region 6 aerial survey program started collecting all geospatial aerial survey data with the Digital Aerial Sketch Map (DASM) system.
Translations for some of the codes on this map:
1-1 = Douglas-fir beetle (code 1) caused tree mortality. There is 1 dead tree in the polygon.
1-5 = Douglas-fir beetle (code 1) caused tree mortality. There are 5 dead trees in the polygon.
4-5 = Fir engraver (code 4) caused tree mortality. There are 5 dead trees in the polygon.
4-10 = Fir engraver (code 4) caused tree mortality. There are 10 dead trees in the polygon.
6W-5 = Mountain pine beetle mortality in western white pine (code 6W). There are 5 dead trees in the polygon.
AB-L = Balsam woolly adelgid (code AB) with light branch flagging.

Using a combination of online and offline surveys will give your research more depth. Learn the difference between the two survey types in the “Battle of the Surveys” infographic below.
All surveys have three key steps:
Create the survey
Collect responses
Analyze the results
Collecting responses is the most important step, as without this, there would be nothing to analyze. Anyone that’s done a survey before will also tell you that it’s also the most tedious step because it is hard to get respondents to well, respond! To get the most possible responses, you need to reach respondents both online and offline.
What is a web-based (online) survey?
Web-based surveys are are available on the Internet and are distributed by sending a URL to respondents by email or promoting the survey through social media, on a website, or on a blog. Your respondents are only those people that you can reach online. For example, you can send a market research survey to those customers that have opted in for your email newsletters.
What is a mobile (offline) survey?
Mobile surveys let you to use touch screen devices like smart phones and tablets to interact directly with respondents in the field. Mobile surveys are optimized for touch screen devices and don’t require an Internet connection to work. Your respondents now become everyone you can reach face to face or in person. For example, you can conduct the same online market research study with any consumer that is on location or in the street.
Which is better?
The answer is that it depends on where your respondents are! If your target market or sample is entirely online, all you need is an online survey. If your target market or sample is only partially online, you shouldn't ignore those respondents that you can’t connect with online. To get the complete picture, you need both web-based and mobile surveys! With our market research example, you would have more accurate results with the opinions of both online customers and those that are on location.
A mid-upper arm circumference (MUAC) measurement is taken to determine the nutrition status of a young child. According to UNICEF (June 2017), an estimated 1.1 million children in South Sudan are acutely malnourished.

For survival analysis it is important not only to mark new females but also to resight previously marked birds. If birds can not be viewed via binoculars or scopes the females will be captured. Band numbers are recorded, culmen, and tarsal measurements are taken, and the female is also weighed.

Data collectors gather information from the selected households, including what they eat, how they earn a living, what strategies they employ to deal with food shocks and more. At the moment, 50% of the population is in need of assistance as a result of not having enough food to eat.

After more than a half-century since its construction, Savannah River Site’s (SRS) R Reactor has taken a leap forward with the introduction of a local wireless Intranet service, even as it undergoes final closure.
The system, known as SRSnet, is used for radiological data collection, time-keeping, safety documentation, and other essential business needs. Prior to the installation of the Intranet Access, 17 teams were required to report to P Area, approximately two miles away, twice daily, for radiological control accountability using software that could only be accessed via the SRSnet.
