7 -Broadband (or BB) sensors are especially sensitive to low-frequency energy and are //broad//ly defined as any instrument capable of **reliably recording wave periods greater or equal to 10 seconds**. This makes them useful for the analysis and detection of teleseismic earthquakes as well as techniques involving ambient noise. However, they are also well-suited for measuring high-frequency energy, limited only by the Nyquist frequency of the [[data logger>>doc:Instrumentation.ANU LPR-200.WebHome]]'s sampling rate. The downside to broadband sensors is usually their cost, size, and fragility relative to short-period sensors.
7 +We usually pack equipment on pallets, in transporter cases, or in boxes. This depends on a range of factors, including:

9 -== Nanometrics ==
9 +* staff and facilities available at your institute
10 +* shipping method (air, sea, road/rail)
11 +* access for inspectors en route (e.g., customs or dangerous goods).
10 10  
11 -Currently, 4 kinds of nanometric broadband seismic sensors are available. The Trillium Compact 120, Trillium Compact 20, Trillium Compact Posthole, and most recently, the Trillium Compact Horizon. These seismometers are ideal for long-term deployments of multiple months. All of these seismometers are compatible with the LPR-200 and TSAWR loggers and are designed for low energy consumption.
13 +In most instances, we provide dimensions for the borrower to quote and book freight directly with their preferred carrier. This simplifies billing and insurance arrangements. However, we will still assist with technical details throughout your booking if needed.

21 +Plan ahead to ensure your teams have the time and tools they need to avoid moving organic material between sites and regions. Factors to consider include site conditions, vehicle capacity, water and laundry access.
20 20  
21 -- Sensitivity?
23 +At minimum, we ask users to follow the basic checklists below for sites in __low-risk__ biosecurity areas. If you are working in higher-risk areas, please discuss your field hygiene plan with us as early as possible, so we can coordinate pre and post-treatments.

29 +1. Brush off as much dirt as possible.
30 +1. Inspect crevices for insects, eggs, seeds, etc.
31 +1. Wipe instruments clean if placing directly into foam or textile cases.
28 28  
29 -The Trillium compact has a recording range between 20 seconds and 100Hz. These instruments also have a tilt tolerance of 10° making for efficient deployment.

35 +1. Check again for insects and loose debris.
36 +1. Check that data cards are removed (and safely stored).
37 +1. Wipe surfaces clean with diluted castile or other mild soap (keeping connectors and electronics dry).
38 +1. Let everything dry well before packing.

41 +Our technicians will clean connectors and tougher stains in the lab.

47 +**Can we pay ANU Earth Imaging to do it for us?**
38 38  
39 -=== Trillium Compact Horizon ===
49 +No, sorry. We recommend 'cleaning as you go' to minimise movement of organic material, and this includes movement back to our territory and campus. We understand this wasn't always considered necessary, and appreciate how quickly and willingly the community has adapted to this change.
40 40

54 +**How clean is clean enough?**
44 44  
45 -Short-period (SP) sensors have limited sensitivity to longer periods, but are otherwise perfectly suitable for earthquake or other high-frequency analysis. They are generally defined as any instrument that begins to **lose sensitivity at periods larger than 10 seconds**. They tend to be smaller and more mechanically robust to broadband sensors.
56 +We will post some example photos soon from our 2025/2026 summer backlog, indicating the standards considered reasonable for low-risk returns.

65 +**More nodes = more cleaning!**
54 54  
67 +In some Australian states, nodes can be installed inside disposable barrier bags to reduce soil contact. We've seen good results in flooded clay sites with 10um bags— the type used for produce.
55 55  
56 -== Channel and Instrument conventions ==
69 +This is only recommended in cases where manual cleaning is not feasible or sufficient.
57 57  
58 -We follow FDSN guidelines for sensor channel and type naming conventions, outlined at [[SAGE / IRIS>>https://ds.iris.edu/ds/nodes/dmc/data/formats/seed-channel-naming/]]
71 +Single-use plastics are not permitted in AoNZ and are being phased out in Australia. If you are considering this option for your experiment, contact us for help navigating:
72 +
73 +* state regulations for single-use plastics
74 +* suitable plastic types
75 +* performance criteria.
