(The additional data point for 2016 shows the mean offset between float pH and hydrocast
pH, the latter acquired during float deployments; Johnson et al.
Currently most of the existing proposed routing protocols in UWSNs such as VBF , DBR , iAMCTD , Hydrocast
 and WDFAD-DBR  are using OR approach in their routing protocols.
During the KX08-973 cruise of R/V KEXUE YIHAO in 2008, seawater column samples and temperature, salinity, and density data were collected at 3 hydrocast
stations (18B 3.6827[degrees]S, 151.8636[degrees]E; 18G 3.7991[degrees]S, 152.1005[degrees]E; and 18K 3.7884[degrees]S, 152.1066[degrees]E) in the eastern Manus basin (Figure 1).
This has been partly due to the limited capability of common hydrocast
steel wire, which could not be safely reeled out more than 96000 m, and therefore could not be used to reach the hadal zone.

The third study used the PTB socket with sleeve suspension and compared it with Hydrocast
HS sockets with Pelite liners.
The author in  proposed the HydroCast
(hydraulic pressure-based any cast) routing protocol to provide a geographic routing solution alternative.
Furthermore, other pressure casting devices, such as the hydrocast
method, can be utilised to evaluate the shape and volume consistency of the pressure casting method.
, a benthic (sea-bottom) grab, and a trawl make up one sample.
has two modes; greedy routing and void handling.
These studies have evaluated interface pressures with patellar-tendon-bearing (PTB) sockets [17-18,20-21], an unrectified hydrocast
socket , and a total-surface-bearing (TSB) socket .
