• Distribution and Reconfiguration of Cognitive Labor in Navigation Team ★★★★★
  The navigation team dynamically distributes tasks among available personnel, with roles iteratively adapted based on skill levels and availability, and the navigator having authority to reorganize the team structure as needed.
  «The navigator is given the authority to reconfigure the navigation team as he sees fit... Unfortunately, the quartermasters were not well enough trained to keep up with the workload, and the chief had to step into the role of plotter.»

• Line of Position (LOP) ★★★★★
  A line drawn on the nautical chart from a known landmark along the bearing observed from the ship, indicating that the ship is located somewhere on that line.
  «Such a line is called a line of position (LOP). If we have another line of position, constructed on the basis of the direction of the line of sight to another known landmark, then we know that the ship is also on that line.»

• Redistribution of cognitive workload across time in navigation ★★★★★
  By performing anticipatory preparations such as chart stacking, pre-plotting tracks, and creating supporting artifacts ahead of high-tempo navigation phases, the cognitive load during critical performance is reduced and managed within team capacity.
  «Because the task is event driven...this is an important strategy for keeping the workload within the capacity of the navigation team. Stacking the charts on the table in the order in which they will be needed is an example of this sort of redistribution of effort across time.»

• Shared Representations as Common Ground for Team Coordination ★★★★★
  Effective coordination within the navigation team and with other units (e.g., Combat Information Center) relies on shared representations such as common charts and track-plots, enabling economical communication and coordinated error checking.
  «Economical encoding of position in relation to the planned track is possible only if both the bridge navigation team and the Combat Information Center have the same track plotted on their charts... The chart is the common ground on which all of these representations can be compared.»

• Triangle of Fix ★★★★★
  The triangle formed by three intersecting lines of position from different landmarks, whose size indicates the quality or certainty of the ship’s position fix.
  «The three lines of position form a triangle, and the size of that triangle is an indication of the quality of the position fix. It is sometimes said that the navigator’s level of anxiety is proportional to the size of the fix triangle.»
• Activity Score Representation for Team Coordination ★★★★
  An activity score visually represents the temporal pattern and coordination of activities across different media and team members during navigation tasks such as position fixes.
  «Figure 4.1 is an activity score for a typical position fix...shows the temporal pattern of activity across the representational media that are involved in the fix cycle...Each fill pattern in the score denotes the activities that involve the coordination of representations of a single landmark bearing.»
• Alidade and Gyrocompass Integration ★★★★
  A telescopic sighting device (alidade) used for measuring visual bearings, combined with a gyrocompass repeater that provides true-north directional reference superimposed on the sight.
  «The observations of visual bearings of the landmarks... are made with a special telescopic sighting device called an alidade. The true-north directional reference is provided by a gyrocompass repeater that is mounted under the alidade.»
• Celestial Navigation and Circles of Position ★★★★
  A navigation method based on measuring the angular distance of stars above the horizon to produce circles of position on which the ship must lie, intersecting to fix the ship's position.
  «By measuring the angular distance of a star above the horizon, an observer can determine his distance from the point on the surface of the earth that the star is directly above. This point forms the center of a circle of position.»
• Cognitive Consequences of Procedural and Environmental Changes ★★★★
  Changes in procedural detail and environmental conditions (such as Sea and Anchor Detail) cause systemic cognitive adjustments including perceptual system organization, error-detection robustness, distributed workload, and reflective supervision.
  «These have a variety of cognitive consequences at the system level, including changes in the organization of the perceptual apparatus of the system to meet anticipated changes in environmental conditions, robust error-detection procedures, increase in work capacity... and self-reflection provided by supervisory functions.»

• Concepts of Set and Drift ★★★★
  Set is the direction of water movement over ground, and drift is the speed of water over ground; both influence navigation by affecting the ship’s actual movement and handling.
  «The direction of the movement of the water over the ground is called the set, and the speed of the water over the ground is called the drift.»
• Coordination through shared temporal and spatial references ★★★★
  Use of shared references such as specific times (Zulu time) and chart positions enables seamless integration of distributed cognitive actions across individuals and artifacts.
  «"Last set still good? OK Ballast Point, light Zulu." "Here s (time) 3 8 (pointing to the DR position on the chart)."»
  связи: hypothesis:H3, type:A
• Coordination under time pressure in navigation activity ★★★★
  The navigation team's procedures require precise timing and coordination, where small deviations (e.g., premature reporting) are tolerated if correction would disrupt workflow during high workload periods.
  «Wheeler’s mistake was not a serious timing error... The important thing was to make the observations as close to the mark time as possible. Stopping to discuss the mistake would have been more disruptive than continuing on.»

• Critique of Individual-centered Cognition Models ★★★★
  A critique of traditional cognitive science and anthropology approaches focusing narrowly on individuals and declarative knowledge, ignoring socio-cultural and practical context.
  «The author critiques traditional approaches that focus on the individual and declarative knowledge, detaching cognition from socio-cultural and practical contexts.»
• Customization and updating of charts by navigation crew ★★★★
  Navigation crews update charts with new landmarks or corrections from periodic notices to improve future navigation tasks, redistributing cognitive effort from performance time to preparation time.
  «The crew of the Palau added a new tower to their chart by establishing bearings...Doing this meant adding workload to one performance…in order to make future performances less effortful or more flexible.»

• Distinction Between Speed Over Ground and Speed Through Water ★★★★
  Speed over ground measures the ship’s velocity relative to land and is influenced by environmental factors like currents, whereas speed through water is the ship’s velocity relative to the surrounding water.
  «The ship’s speed over the ground may be very different from its speed through the water because the water itself may be moving.»
• Ethnographic Analysis of Navigation Teams ★★★★
  A methodological approach involving detailed observation and analysis of navigation teams in real-world settings to understand integrated cognitive systems.
  «The main methodology is ethnographic observation and detailed activity analysis in natural conditions using cognitive anthropology concepts.»
• Fix Interval as Sampling Parameter in Navigation ★★★★
  The fix interval is a configurable parameter that controls the rate of environmental sampling during navigation; a default interval (e.g., 3 minutes) simplifies computations but can be shortened for higher resolution, reflecting a trade-off in task performance.
  «The default fix interval is 3 minutes because this permits the simplification of certain computations. This interval can be made shorter by the navigator if more resolution is required. The fix interval is a parameter that controls the rate of sampling the environment.»

• Pelorus Operators' Role and Preparation ★★★★
  Pelorus operators must be familiar with navigation aids, maintain appropriate clothing for exposure, test sensors timely, and operate in coordination with the navigation team during Sea and Anchor Detail.
  «The pelorus operators must acquaint themselves with the navigation aids so that they will be able to find them when directed to shoot bearings...they are expected to stay at their posts for the duration of Sea and Anchor Detail...it is important that pelorus operators dress appropriately...»
• Permanent chart annotations for navigation ★★★★
  Markings such as projected tracks, critical depth contours, turn bearing landmarks, and anchorage approaches are drawn permanently on charts to reduce cognitive load during navigation by externalizing calculations and decision points.
  «These features of the planned route of the ship do not change from one entry of the harbor to another, so they are often plotted on the chart in ink.»
  связи: hypothesis:H3
• Pre-assembly and ordering of navigation charts ★★★★
  A method of arranging all required navigation charts in advance on the chart table, stacked in the order they will be needed, allowing quick chart changes during ship maneuvers without time-consuming searches.
  «All the charts that will be needed for a particular detail are assembled ahead of time and arranged on the chart table, one over the other, in the order in which they will be needed.»

• Procedural Stability vs. Actual Task Performance in Navigation ★★★★
  The written watch standing procedures provide a stable normative framework for describing the navigation team system, but they are not directly used by team members to structure tasks or describe actual performances, and rigid adherence would render the system nonfunctional.
  «The written procedures are not used by the members of the navigation team as structuring resources during the performance of the task, nor do they describe the actual tasks performed. Furthermore, if a system was actually constructed to perform as specified in the procedures as written, it would not work.»
  связи: type:C
• Radar Position Fixing ★★★★
  Using radar range (distance) and bearing measurements to detect nearby objects and plot position fixes by plotting circles of position, often combined with visual bearings.
  «Radar ranges are more accurate than radar bearings, so they are given priority in position plotting. In practice, radar ranges plotted as circles of position are often combined with visual bearings to produce position fixes.»
• Role of the Plotter in Navigation Team ★★★★
  The plotter is responsible for recording and providing navigational information selectively based on the needs of the Officer of the Deck (OOD), anticipating information requirements to support decision-making.
  «The first three duties of the restricted-maneuvering plotter are straightforward... they are provided when they are thought to be of use to the ODD. This requires the plotter to know something about the nature of the work being done by the ODD...»

  связи: type:E
• Use of advance and transfer tables for ship maneuvering ★★★★
  Specialized tables provide empirical data on ship handling characteristics (advance and transfer during turns), simplifying cognitive computations needed for plotting accurate navigational tracks and maneuvers.
  «The advance and transfer tables make it easier to plot the projected track...by specifying the changes in the cognitive requirements of the tasks that must be performed.»
  связи: type:E
• Constraints on Position Fixing During Ship Turns ★★★
  Taking position fixes while the ship is turning presents difficulties due to observation inaccuracy from a moving platform and unreliable projection of future position, leading to the practice of avoiding fixes during turns and waiting for steady courses.
  «There are two problems with fixes taken while the ship is turning. The first is that it is difficult to make accurate observations from a turning platform... The second problem is that even if they can be made accurately, they are a poor basis for the projection of the ship’s position in the future.»
• Deviation table for compass error correction ★★★
  A table empirically constructed ahead of time to record the magnetic compass deviations at various headings used to compensate for inherent compass errors caused by ship's electromagnetic environment.
  «A deviation table is constructed. The error of the compass on headings at 100 intervals is observed empirically and entered into a table.»
• Embodied pointing to charts as cognitive artifact manipulation ★★★
  Physical gestures toward charts (e.g., pointing to DR position) function as part of the externalized cognitive process, anchoring communication and situational awareness.
  «"Here s (time) 3 8 (pointing to the DR position on the chart)."»
  связи: hypothesis:H3, mode:modularity
• Error Correction Protocol in Navigation Logs ★★★
  A formalized procedure where errors in the bearing record log must be line-through corrected (both the original and correction remain legible), maintaining the integrity and traceability of navigational data.
  «If an error is made, the recorder must draw a line through the entry that is in error and enter the correct information leaving both entries legible.»

• Fathometer Depth Measurement ★★★
  An acoustic device measuring depth by emitting sound pulses and recording the time it takes for echoes to return from the sea bottom, providing a continuous graph of water depth under the ship.
  «The fathometer... emits a pulse of sound and measures the time it takes the sound pulse to bounce off the sea bottom and return to the ship. This results in a continuous graphical record of the depth of the water under the ship.»
• Micro-dialogues as coordination mechanism ★★★
  Brief verbal exchanges, like confirming times and positions, serve as real-time coordination tools among navigation team members to synchronize cognitive processes.
  «"1. S: Last set still good? OK Ballast Point, light Zulu." "2. C: Here s (time) 3 8 (pointing to the DR position on the chart)."»
  связи: type:C, hypothesis:H1
• Navigation Recorder's Functionality ★★★
  The navigation recorder is tasked with keeping continuous and accurate records of bearings, times, and other navigational data following instructions and avoiding the use of information from previous operations that could bias current recordings.

• Omega Navigation System Caution ★★★
  An early worldwide radio navigation system perceived as unreliable, acknowledged with strong procedural warnings despite its presence on the ship due to prior military investment.
  «Whatever the source of the problems... a strongly worded caution appears in the Watch Standing Manual... this system is considered to be so unreliable... still it was bought and paid for by the military, and can, on occasion, provide useful navigation information.»
• Precomputation of the Intended Track ★★★
  Precomputing the ship’s intended track simplifies the determination of the vessel’s position relative to that planned course, enhancing cognitive efficiency in navigation.
  «The determination of the relation of the ship to the intended track is greatly simplified by the precomputation of the track.»

• Redundant Recording by Fathometer Operator ★★★
  A redundancy practice where the fathometer operator logs soundings independently in a sounding log, ensuring data reliability and cross-verification within the navigation system.
  «The fathometer operator makes a redundant recording of the soundings in the sounding log.»
  связи: hypothesis:H3, tension:generation-vs-verification
• Role flexibility influenced by crew experience ★★★
  Functional roles within the navigation team can be adapted based on crew experience and staffing, exemplified by the Assistant to the Navigator acting as navigation plotter due to understaffing and inexperience.
  «Because the Palau was understaffed and personnel inexperienced, the Assistant to the Navigator also served as navigation plotter.»
  связи: tension:autonomy-vs-control
• Trade-offs in Navigation Aids Labeling Schemes ★★★
  Labeling navigation aids alphabetically benefits the plotting table but imposes cognitive costs on pelorus operators who must memorize arbitrary landmark names, exemplifying organizational trade-offs.
  «This lettering scheme is an example of a feature that benefits one part of the organization while putting costs elsewhere...Some quartermasters have remarked that this can be a real problem going into a foreign port.»
• Use of analog instruments for bearing measurement ★★★
  Operators use specialized analog tools such as the alidade mounted on pedestals and a one-armed protractor ('hoey') to measure and plot bearings on charts by aligning with landmarks and gyrocompass readings.
  «Wheeler’s hands were resting on the alidade mounted on a shoulder-high pedestal... Chief Richards held in his hands a one-armed protractor called a hoey... used to construct lines on the chart that correspond to the lines of sight between the ship and landmarks.»
• Use of synchronized timing devices for coordinated observations ★★★
  The navigation team synchronizes digital wristwatches to the ship’s clock to coordinate the timing of bearing observations precisely, enabling consistent temporal markers for position fixing.
  «He had synchronized it with the ship’s clock... Silver took the watch off his wrist and placed it on the chart table just above the bearing record log to maintain time.»
