“It is well known that the ocean acoustic wireless channel is extremely challenging due to the severe multipath propagation, large Doppler spread, and high Doppler-to-Carrier Frequency ratio. In recent years, advanced physical-layer techniques, such as advanced coding and equalization, Orthogonal Frequency-Division Multiplexing (OFDM), and single-carrier modulation scheme are proven to be effective in combating the channel impairments and achieving reliable communication with high data rates.

Albeit that many research papers are well-written and well-articulated in recent years, re-producing the advanced scheme for underwater communication system is often a daunting task, especially for junior researchers who lack solid background in digital (wireless) communications and adaptive signal processing. This tutorial provides a practical course for entry-level researchers to learn several basic signal processing techniques for underwater acoustic channels. The targeted audience is graduate students and researchers who would like to gain practical experience with acoustic communications using both simulated numerical examples and at sea data.

This tutorial will not only cover the basic theory and algorithms, but also emphasize hand-on exercise. Students are paired in teams by their complimentary background and compatible Matlab skill levels. Sample codes are provided and short lab exercises are used to walk students through the essential building blocks of one or more complete transmitter and receiver systems. Students are required to bring their own laptop computers with Matlab version 2014 (or later versions) installed.”

A Simple FPGA based underwater telephony. A hands on demonstration of the product. High speed communication in underwater scenario is a very challenging task. Huge power degradation and large attenuation of electromagnetic waves in water renders them unsuitable for underwater communication. Among others the acoustic signals are mostly used for this purpose, but they also get attenuated and absorbed a lot in medium. Transmission is limited by range dependent bandwidth, severe multipath, large fading and large and differential Dopplershifts. Many methods have been suggested to enhance the data rate and to reduce Bit Error Rate (BER) in typical underwater communication environment, but the task of achieving high-rate is still open. One of the state-of-the-art solutions devised to solve is Time Reversal Mirror (TRM). TRM is a broadband beamforming at transmitter side that exploits the reciprocal property of sound wave equation. Active TRM communication system utilizes spatial diversity at transmitter rather whereas, passive TRM uses receiver diversity. It reduces the complexity of the receiver by focusing the energy in time and space. Orthogonal frequency domain Multiplexing is another technique to solve this challenging task, but the frequency dependence of this technique in highly Doppler underwater environment possess another challenge. In this demonstration we will show the real time underwater telephony for a range of 5km at a rate of 5kbps using 10kHz of bandwidth.

The USACE Charleston district has been using backscatter data from uncalibrated multibeams to determine the locations of objects in the Charleston Harbor and surrounding projects. The addition of multifrequency sonars to the workflow has allowed the creation of multispectral backscatter which has provided even better imagery to identify objects such as dredge pipe which may pose a danger to dredging operations and navigation. The greatest benefit of the workflow developed has been that objects can be detected using the same data collected for pre- and post-dredge surveys or standard condition surveys already being performed by the district. Thus, backscatter has allowed the district to leverage already collected data for additional purposes. Additionally, other possibilities of utilizing multispectral backscatter data such as determining the locations of change in bottom type to reduce the amount of bottom sampling performed for feasibility studies or determining locations of fluid mud by monitoring the divergence in low and higher frequency multibeam data are still being investigated.

Deep Learning is an important and emerging field that is getting an attention from all application domains. Current interest in deep learning can be considered a second era renaissance of neural networks. Until the late 90s, researchers were trying to identify reliable method to train very deep and better neural networks and with the development of simple yet important theoretical and algorithmic developments, the advances in hardware (GPUs), and advent of Big Data, Deep Learning fills the gap required for this transformation in machine learning.

Purpose of this short course is to introduce basics and applications of Deep Learning so that participants can have an idea about how to utilize deep learning techniques in Ocean applications. The tutorial will start from the very basics of machine learning, introduce neural networks and provide hands-on exercise with deep learning primitives. The intent is to provide an overview that will enable the participant interested in more details to investigate them through primary references provided. Examples of applications from image processing and acoustics domain will be provided so that the participant will obtain a basic understanding of the topic and its applicability.

High costs of ship operations compounded with their inherent operational limitations as well as risks to human health and life emphasize the need for more cost-efficient and scalable alternatives for marine ecosystem surveying, monitoring, management, and conservation. This half day workshop will explore emerging technologies suited to provide such services while reducing operational risks and costs and improving operational availability, efficacy, and cost-efficiency. Examples of relevant topics may include, but are not limited to innovative robotic platforms, such as autonomous aerial, surface, and underwater vehicles, smart sensor technologies, including in-situ survey, mapping and remote sensing tools, adaptive survey techniques through analytical decision support, optimal information utilization, and cross-platform coordination, as well as intelligent data analysis, efficient communications, and other related technologies and methodologies. Through a series of presentations, a moderated panel, and an town hall discussion, our workshop will explore such innovations and what is needed to accelerate their adoption and bring them into the mainstream use by the practitioners in the field. Additionally, this workshop will provide an opportunity to explore how the role of conventional survey and research ships will evolve with the introduction of more scalable, cost-efficient, and intelligent autonomous platforms, instruments, and analytical technologies, and what new roles and functions may be allocated to ships as a result of these developments. A discussion panel , moderated by Dr. Victor Zykov, Director of Research at Schmidt Ocean Institute, will highlight insights and unique perspectives on scaling up marine surveying, management, and conservation with cost-efficient, accessible innovations from a representative group of technology developers, engineers, designers, makers, and program directors working on ASVs, e.g. Saildrone, Wavegliders, UAVs, e.g. Flightwave and Latitude Engineering, low-cost ROVs, AUVs, and other platform, sensor, communications, and data technologies.

The OGC and ISO Observations & Measurements (O&M) conceptual model avoids over constraining information objects by allowing variability. Where variability exists, interoperability is often compromised for individual use-cases. When implementing systems that produce O&M compliant data flows, developers must make localised decisions on how to implement O&M. Often these implementations are non-standardised and diminish the possibility of applying the: collect, use, use multiple times philosophy.

Two-level modeling introduces the concept of archetypes. Archetypes can allow extensions or profiles of O&M to be agreed, documented and published within a diverse community of specialists. A key differentiator of two-level modeling compared to other approaches is that it allows domain experts to be the primary drivers of digital artefacts (not developers), while also ensuring that technical validity is maintained in one highly accessible and integrated process; leading to a managed and interoperable extensibility mechanism to standards such as O&M.

In this workshop we explore the two-level modeling methodology applied to ocean observing activities. Participants will be guided through a two-level modeling exercise, where they will gain the basic knowledge needed to engage in a two-level modeling activity. Participants will then gain hands on experience of the two-level modeling process and the art of developing archetypes for a use-case on top of the O&M conceptual model. During this workshop we re-imagine the INSPIRE Marine Pilot use-case using a two-level modeling methodology.

Participant Learning Outcomes
On completion of this workshop participants will be able to:
— Identify the challenges of maintaining semantic interoperability between different O&M implementation scenarios.
— Appreciate the potential of two-level modeling and archetypes for solving semantic interoperability issues.
— Describe the basics of two-level modeling and archetypes.
— Understand the basics of the two-level modeling process and the purpose of additional two-level modeling supportive patterns within O&M.
— Apply basic archetyping techniques to model concepts within a diverse group of non-technical stakeholders for a given use-case.
Workshop Aims
— Engage the ocean monitoring community in a discussion about the potential of archetypes.
— Demonstrate the two-level modeling process as applied to the O&M standard.
— Provide participants with hands-on experience of creating archetypes for a given use-case/observation scenario.
— Gain feedback from participants to inform future directions and programmes of work.

In the value chain of progressing from data to information to applications and knowledge, observations of surface ocean and coastal water properties by satellite remote sensing are significant components for many operational applications, modeling and data assimilation activities, and scientific investigations that assess, monitor and predict the physical, biological, and biogeochemical states of the marine environment. For the open ocean, many key environmental p1arameters are determined on a routine and sustained basis from well-validated algorithms including sea surface temperature, sea surface height, ocean color, sea ice, ocean winds, and roughness of the ocean surface (e.g., oil spills), providing frequent and synoptic coverage. Retrievals in coastal, near-shore and inland waters continue to be an area of active research and development, but many products are fit for purpose and ready for use in observation-based marine applications. Gaining access to and utilizing these satellite data and data products can be daunting to the non-specialist, however. This tutorial will i) review current status and availability of mature, operational satellite observations for the ocean and coasts; ii) provide information on emerging satellite-derived products; iii) illustrate use of these data through representative case studies; and iv) highlight methods for the discovery and acquisition of satellite data, including a demonstration of the NOAA CoastWatch/OceanWatch/PolarWatch data portal and a group discussion on solutions to the barriers (real or perceived) that constrain more routine utilization of satellite observations. Time will be allocated for participants to explore data portals and interact with the tutorial team to request guidance, suggest downstream data products and/or give feedback, etc.
